Question

PLEASE HELP 33 POINTS AND I WILL MARK BRAINLIEST!!!!!!!! THANKS!!!!!!!!!!!

Answer 1

(a) Volume of any Pyramid =   $\frac{1}{3} * (Base-Area)*height = \frac{1}{3} *220.22*9 = 660.66$ cubic units

(b) Sarah doesn't have to go through all the hard work as the smaller pyramid has a ratio of 2:3 to the bigger pyramid, so we get the equation, to help us solve it.

$660.66 = \frac{2}{3} *(Area-of-larger-pyramid)$

Hope that helps!
