The volume of a pyramid whose base has a surface area B%7D%7D+%0D%0Ais+%7B%7B%7B%281%2F3%29%2AB%2Aheight .
It is calculated the same way,
whether it is a right pyramid (with apex directly above the center of the base),
or an oblique pyramid (with apex not directly above the center of the base).
In this case the surface area of the base (in square cm) is
B=x%2Ax=x%5E2 , and height (in cm) is height=x%2B2 ,
so the volume, in cubic cm, is
.
