Question

A regular square pyramid is $3m$. height and the perimeter of its base is $16m$. Find the volume of the pyramid.

Answer 1

Given that,

Height of the pyramid $h=3m$

Perimeter of the base $=16m$

$⟹(a{)}^2=16$

$⟹a=4m$

Volume of the pyramid $=\frac{1}{3}\times (a{)}^2\times h=\frac{1}{3}\times (4{)}^2\times 3=16m^3$
