Answer
$V=960$ cubic centimeters
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, $s=12$ cm and $h=20$ cm.
$V=\frac{1}{3}s^{2}h$
$V=\frac{1}{3}(12)^{2}(20)$
$V=\frac{1}{3}(144)(20)$
$V=(48)(20)$
$V=960$ cubic centimeters
