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

Answer:
c
Step-by-step explanation:
The volume (V) of a square based pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h is the height )
Here V = 1350, thus
[tex]\frac{1}{3}[/tex] × 15²h = 1350 ( multiply both sides by 3 to clear the fraction )
225h = 4050 ( divide both sides by 225 )
h = 18 ft → c
