Question

What is the volume of the square pyramid with base edges 18 m and slant height 15 m

Answer 1

check the picture below.

so it has a base of 18x18 and a height of that much.

$\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=area~of\\ \qquad its~base\\ h=height\\ ------\\ B=\stackrel{18\times 18}{324}\\ h=12 \end{cases}\implies V=\cfrac{1}{3}(324)(12)\implies V=1296$

Answer 2

The answer is 1296
