Question

What is the volume of the rectangular pyramid?

720 ft3

540 ft3

360 ft3

1080 ft3

Answer 1

360 ft³

Explanation:

The formula of a volume of a pyramid:

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

B - area of a base

H - height

In the base we have the rectangle 12ft × 6ft.

Therefore

`B=(12)(6)=72\ ft^2`

H = 15 ft

Substitute:

`V=(1)/(3)(72)(15)=((72)(15\!\!\!\!\!\diagup^5))/(3\!\!\!\!\diagup_1)=(72)(5)=360\ ft^3`
