Question

Sam has two figures, one square pyramid and one rectangular prism. The pyramid has a height of 6 inches and a base length of 4 inches. The rectangular prism has a length of 8 inches, a width of 2 inches, and a height of h inches. If both figures have the same volume, what is the height of the rectangular prism?

Answer 1

Answer:

1/2 inches

Step-by-step explanation:

Volume of a pyramid: (LWH)/3

Volume of a rectangular prism: L*W*H

So if the volumes of both shapes are equal then

(lwh)/3=lwh

Lets substitute the numbers give in the problem into the formula

6*4/3=8*2*h

24/3=16h

8=16h

Divide both sides by 16

8/16=h

1/2=h
