My name is Cone. I think my classmates have heard about it. My head is pointed and my ass is round. It looks funny. The distance from my apex to the bottom center is my height. Remember, I'm not like a straight column They are several tall, but I only have one. But I don't envy them, because I only have one height to be different! Oh, I forgot to tell you that it is a fan when cutting along my bus. If you look at my front carefully, is it an approximate triangle? In fact, as long as one right-angled side of a right-angled triangle is rotated quickly, the figure formed is me!

Next, I will tell my classmates about my volume calculation method. First of all, I'd like to introduce my brother, Gang. According to the measurement, if our base height is equal, my volume is one third of its volume. Students have learned the calculation method of cylinder volume, saying that my volume can only be calculated by the bottom area × height ×. For convenience, I will also tell you the letter formula for calculating my volume: V= SH. But some students always forget to bring it when calculating my volume, so it is not my volume. Not only will I be angry, but I may also cause careless students to get full marks. You don't have to recite my paper, but you have to learn and use it in your life!

I wonder if the students have found that some buildings and hats imitate my body structure! This makes me very proud!

So much for my self-introduction. If you are interested in me, you should actively explore. Looking forward to your discovery and "achievement", I believe all of us will become good friends!
