Question

Find the volume of a rectangular pyramid 7 in. high and a base measuring 9 in. by 2 in.

Answer 1

Given;

The height of the pyramid is, h = 7 in.

The length of the base is, l = 9 in.

The width of the base is, w = 2 in.

The objective is to find the volume of the rectangular pyramid.

Step-by-step explanation:

The general formula to find the volume of a rectangular pyramid is,

`V=(l* h* w)/(3)`

Substitution:

On plugging the given values in the general equation,

`\begin{gathered} V=(9*7*2)/(3) \\ =(126)/(3) \\ =42in^3 \end{gathered}`

Hence, the volume of the rectangular pyramid is 42 cubic inches.
