Question

If the area of base of a rectangular based pyramid is $60m^2$ and its height is $7.5$ m, find the volume.

Answer 1

The general formula for volume of pyramid is $V=\frac{1}{3}Bh$, where $B$ is the area of the base and $h$ is the height.

Since the area of the base is $B=60$ m${}^2$ and the height $h=7.5$ m

Therefore, the volume is:

$V=\frac{1}{3}bh=\frac{1}{3}\times 60\times 7.5=150$ m${}^3$

Hence, the volume of the pyramid is $150$ m${}^3$.
