Volume of a pyramid
How do you find the volume of a pyramid. The formula equals 1/3 x base x height. There are two important points to remember when finding the volume of a pyramid.
First, the formula for finding the base will vary according to the shape of the base.
Here is a helpful link for a list of most base area formulas.
Second, the height is actually the altitude of the pyramid.

Use the formula 1/3base area times height in order to find the volume of a pyramid.
The video explains how you first find the base area and then the height of the pyramid and add these together and you have the volume
