Question

A square pyramid with a height of 7 inches has a volume of 47.25 cubic inches. Find the side length of the square base.

Answer 1

Answer:

4.5 inches

Step-by-step explanation:

volume= 1/3 (base area) × height

47.25= 1/3 ( base area) × 7

20.25 = base area

now since the base is a square we can evaluate base area = length²

20.25= length²

length = 4.5 inches
