Answer 5 / 32
Step-by-step explanation:
I am sorry but i don't know, But the student won 32 times. I did the math on paper and then on my calculator. I am really sorry i couldn't help you. 'ω' Hope you do good on this question and again sorry i could not help you.<span />
To solve this problem you must apply the proccedure shown below:
By definition, an equilateral triangle has equal sides and all its internal angles are
. If you divide it into two right triangles, you can apply the Pythagorean Theorem to calculate the height of the triangular base of the pyramid, as following:
![h=\sqrt{18in^{2}-9in^{2}}\\ h=15.58in](https://tex.z-dn.net/?f=%20h%3D%5Csqrt%7B18in%5E%7B2%7D-9in%5E%7B2%7D%7D%5C%5C%20h%3D15.58in%20)
Therefore, as you can see, the answer is:![15.58in](https://tex.z-dn.net/?f=%2015.58in%20)
Answer: 69.3
Explanation: So if the height is 13.1, that means that the length is 2.3. And to find volume, you do length times width times height. So the width would be 2.3 because it is a even square if that makes since. Now 2.3 times 2.3 is 5.29. Now we multiply 5.29 by 13.1. The answer is 69.299. Now we round this to the nearest tenth, so the answer would be 69.3.
