Question

A square pyramid has a base edge of 15 in. If the height of the volume is 12 in find the volume of the pyramid

Answer 1

Volume of the square pyramid is given as,

$V=\frac{1}{3}Bh$

where,

$\begin{gathered} B=\text{ area of the base.} \\ B=a^2 \\ B=15^2 \\ B=225in^2 \end{gathered}$

So, the volume is,

$\begin{gathered} V=\frac{1}{3}\times225\times12 \\ V=225\times4 \\ V=900in^3\text{ } \end{gathered}$
