There is a thing, the bottom is nine centimeters long, six centimeters wide, and three centimeters high.

At first glance, this topic is a simple problem of finding the area of a cuboid, and I also made the end of the water-filled geometry to figure out the mystery. Pen, fun, and www.biquge.info

The simple problem of multiplying the base area by the height did not stump Zhou Zheng, and the area of the cube behind it was equally simple.

It wasn't until the last question of calculating the volume that Zhou Zheng suddenly had a feeling that it was the same thing.

Sikong Jingsu's last question is to find the volume of a cylinder, which has not been learned at all in the previous class, and there must be a lot of pressure on the following students.

Zhou Zheng's idea is very simple, this topic must be the finale as the last question, but it is not too difficult, Da Sikong's move must be to test who has turned the back of the book.

At this moment, Da Sikong sat on the chair in front of him, looking down, and many students fell into a state of anxiety.

The first two of the three questions were very simple, except for the last one, which was beyond their comprehension.

Multiplying the base area by the height gives the volume, and everyone knows this problem, even Sikong Tu, who is not willing to study hard.

But the most important thing is that no one knows how the area of this circle is calculated!

Looking at the somewhat anxious students below, Sikong Jingsu didn't say anything, he wanted to see who would double his books in his free time, instead of lingering in the land of fireworks after class every day.

Unlike the sad faces of other students, Zhou Zhengke doesn't have so many things, it's not just a circle area, 3.14 times the square of the circle radius can get the area of a low circle.

Then multiply the area of the low circle by the high and you get the answer you need.

Zhou Zheng quickly completed all the questions assigned by Sikong Jingsu, and began to secretly see the reactions of others.

Sure enough, everyone else fell into the last question, hehe, these people, they were very serious when they went to class one by one, who knew that after class, they all ran there to mess around!

Alas, this damn adolescence.

When Zhou Zheng secretly peeked at others, with such a light glance, he saw the appearance of Sikong Tu scratching his ears and cheeks in front of him, and it was estimated that Sikong Tu would not be able to do it.

However, who made you Sikong Tu my best friend, so I reluctantly mentioned it secretly.

The formula for the area of a circle is in the book, but you have to turn to the back to see it, although these nobles come to class every day, but how can they read books after they go back!

Of course, although the master never read the books sent by the masters after he went back, he at least read the books after he went back.

Invisibly, Zhou Zheng pretended to be a perfect force in his heart, and suddenly felt that his force had risen several levels.

Secretly looked ahead, only to see that Sikong Jingsu was still looking at the students in front of him gracefully, and did not look behind.

Immediately, Zhou Zheng lowered his body and lay down to point out the Sikong disciple who was scratching his ears and cheeks.

Just as Zhou was about to speak quietly, Sikong Tu in front of him suddenly leaned his body back, approached the table and tilted his head back.

"Boss, this last question is too difficult, please point me brother!"

Sikong Tu said this to reveal his true feelings, and put all his hopes on Zhou Zheng's body.

There is no way, who made Zhou Zheng suddenly seem to be a different person in the past two days, and began to study hard to be a good student, such a change made Sikong Tu subconsciously think that his eldest brother began to focus on studying.

For Sikong Tu's sudden move, Zhou Zheng was taken aback, and he was still observing the situation in front of him, and his attention was extremely concentrated, for fear that something would attract Sikong Jingsu's attention.

As a result, he was afraid of something, not only did Sikong Tu say this, but even a message flashed in his mind.

In the light screen in his mind, Zhou Zheng suddenly released a task again.

"Ding Dong, daily quest release, one: Assist Sikong Tu to complete his homework, and the task rewards one hundred summon points.

Two: The pit is empty, and the task rewards 500 summon points. ”

As soon as he saw the news released by the system, Zhou Zheng immediately made his own decision, decisively choosing between selling his teammates and helping his teammates.

This reward means that you can't give up at all, and after completing it, it means that you are one step closer to unblocking Lu Bu.

"The last question? Simple, the answer is 141.3 cubic centimeters. ”

As soon as Sikong Tu heard the answer, he immediately wrote the answer on a piece of paper with joy, completely unaware that he had walked into a trap.

"Alas, for the sake of the summoning point, I can only choose to pit you."

Among the two options of selling teammates and selling teammates, Zhou Zheng decisively chose to sell his teammates.

After Sikong Tu happily wrote out the answer, Sikong Jingsu looked at it from above, and many students were confused.

Such an effect is exactly what Sikong Jingsu needs.

"Did any of you make the last question?"

Sikong Jingsu's angry voice suddenly sounded in the classroom.

When the students below heard Sikong Jingsu's voice, they immediately took their eyes off the question and put it on the blackboard.

Looking at the blank looks of these students below, Sikong Jingsu knew that these students would definitely not know this last question.

"Da Sikong, Sikong said he would be the last one!"

Silence, deathly silence!

The words that suddenly sounded directly pushed Sikong Tu above the cusp of the wind and waves.

Many students' eyes looked at Sikong Tu, and from their eyes, it was not difficult for Sikong Jingsu to see a trace of disbelief, as well as doubts about talking.

Those of us who are serious in class have not come up with a problem, how can you solve it without learning countless guys, there must be some ghost in this!

It is not difficult to imagine Sikong Jingsu, there must be people who think that they have quietly supported their own grandson, these noble children, one by one, are very shrewd.

"Da Sikong, since Sikong will be a disciple, why don't you let Sikong disciple explain this topic to us well?"

Below the classroom, such a voice suddenly came out, and Sikong Jing looked at it calmly and saw that it was Wang Zhi, the youngest son of Wang Jixiu, the eldest doctor.

Doctor Qing is considered to be the auxiliary minister of the Son of Heaven in the court, but it is still a little worse than himself, and it is not difficult to see a trace of unconvincing from Wang Zhi's eyes.

Wang Zhike doesn't think that he is as good as Sikong Tu, a person who does not learn countless things.

After Wang Zhi's words were mentioned, Sikong Jingsu also let his grandson stand up, he wanted to see how his grandson solved the last question.

The Sikong disciples who stood up were obviously a little forced, isn't it just such a simple thing as an answer, one by one?

Immediately, Sikong said: "Back to Da Sikong, the answer to the last question is 141.3 cubic centimeters. ”

After standing up, I don't know why, Sikong Tu's heart is always a little uneasy, but he doesn't know why.

Well? After Sikong Tu's words came out, Sikong Jingsu was full of disbelief that this grandson of his had really calculated it.

"Oh? Tell me how it was calculated? ”

How is it calculated? Damn, how do I know, I can't say it's the answer the boss told me!

At this time, Sikong Tu knew why there was always a faint uneasiness in his heart, and only now did he suddenly realize that he had only one answer and no process.

It's embarrassing!

Sikong Tu, who stood up, blinked his eyes but didn't know what to say.

The eyes of everyone in the entire academy were on Sikong Tu's body, but Sikong Tu didn't say a word for a long time, which couldn't help but arouse Wang Zhi's suspicions.

"Brother Sikong, what is this process? Come on, don't hang the appetite of our people, you don't know, right? ”

Wang Zhi's voice had a slight hint of ridicule, which made Sikong Tu a little angry, damn it, isn't it just a question, as for such ridicule?

Sikong Tu was about to fight back, but suddenly a word came from his ears, and he forcibly held back what he was about to say, and turned to other words.

"Hmph, on page 167 of the book, I read it myself, I never read a book, what qualifications do I have to question it?"

Sikong Tu's words did not give the king any face at all.

And after Wang Zhi listened to Sikong Tu's words, he immediately blushed, he Wang Zhi thought that he was also a good student in the eyes of his master, why was it his turn to mock himself now.

Immediately, Wang Zhi opened the book heavily, he wanted to see if this Sikong disciple was bluffing!

The conflict between Wang Zhi and Sikong Tu, Sikong Jingsu saw it, but he did not make any obstacles.

Wang Zhi confidently opened page 167 of the book, he wanted to let Sikong Tu know the consequences of his nonsense.

After the 167th page of the book was opened, it was the original question on the bamboo board, and it was exactly the same as the process answer, so wouldn't his previous actions be like a clown!

Wang Zhi, who was angry, couldn't bear such a gap, and an excellent student in his own hall was actually educated by Sikong Tu, a person who does not seek to improve, today.

How could he bear it!

Immediately, Wang Zhi, who was angry, was fainted by anger.

When he fainted, Wang Zhi faintly heard Sikongtu's shout.

"Oh no, Wang Zhi couldn't stand such a blow and fainted!"

"Sikong Tu, my Wang Zhi and you are incompatible...... Wang Zhi had his last thought before fainting.

"Ding Dong, daily missions 1 and 2 have been completed to obtain 600 summon points, and there are currently 9700 summon points left, please continue to work hard."

"Haha, it's a no-brainer!"

Someone's smug voice suddenly sounded in his heart.
