Answer
$V=163\frac{1}{3}$ cubic inches
Work Step by Step
The formula for the volume of a square-based pyramid is $V=\frac{1}{3}s^{2}h$ where $s$=length of the side and $h$=height. According to the data, $s=7$ in and $h=10$ in.
$V=\frac{1}{3}s^{2}h$
$V=\frac{1}{3}(7)^{2}(10)$
$V=\frac{1}{3}(49)(10)$
$V=\frac{490}{3}$
$V=163\frac{1}{3}$ cubic inches
