Question

Find the height of the pyramid. square base with edge 15 feet and volume 1,350

Answer 1

c

Explanation:

The volume (V) of a square based pyramid is calculated as

V =
`(1)/(3)` Ah ( A is the area of the base and h is the height )

Here V = 1350, thus

`(1)/(3)` × 15²h = 1350 ( multiply both sides by 3 to clear the fraction )

225h = 4050 ( divide both sides by 225 )

h = 18 ft → c
