Question

What is the volume of a square pyramids

Answer 1

`\large\boxed{V=75\ in^3}`

Explanation:

The formula ogf a volume of a pyramid:

`V=(1)/(3)BH`

B - area of a base

H - height

We have a base length a = 5 in and a height H = 9 in.

In the base we have a square. The formula of an area of a square is:

`B=a^2`

Substitute:

`B=5^2=25\ in^2`

Calculate the volume:

`V=(1)/(3)(25)(9)=(25)(3)=75\ in^3`
