Answer 2

Hey there @Yaquelin

Do you know the formula to find the volume of a pyramid?

Answer 3

Volume of a square pyramid = (base length* base length * height)/3

Or more simply
volume (sq. pyramid) =\(\sf\frac{(base~ length)^2 \times height}{3}\)

Answer 4

Find the volume for Pyramid A.

Then to find how many times bigger volume B is than volume A:

\(\sf\frac{Volume~B}{Volume~A} \)

Multiply it by 100% to get it as a percentage.

Let me know if you understood that or want more clarification.

I'd be more than happy to check your work/answer.

Answer 5

Err I'm sure you understand that when I said Volume B, I meant Volume of Pyramid B
And similarly for Volume A, it should be volume of Pyramid A. But just in case you didn't get that (:
