Question

Square pyramid has a volume of 20 cubic feet and a base length of 5 feet. What is it's height?

Answer 1

2.4 ft = height

Explanation:

The formula for the volume of a pyramid is V = (1/3)(base area)(height).

Here V = 20 ft² = (1/3)(base area)(height).

Since the base area is (5 ft)², or 25 ft², 20 ft² = (1/3)(25 ft²)(height),

(height) = (20 ft³) / ( [25/3] ft², or 60 ft³ / (25 ft²) = 2.4 ft = height
