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

erastova [34]

Answer:

The height of the pyramid is $2.4\ ft$

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

we have

$V=20\ ft^{3}$

$b=5\ ft$

substitute and solve for h

$20=\frac{1}{3}(5)^{2}h$

$60=(25)h$

$h=60/(25)=2.4\ ft$
