Volume Formulas

Prism

Finding the volume of a general prism is a matter of multiplying the area of the base times the height of the prism:

Volumegeneral prism = A H

Identify the variables: x

A = Area of the base

H = Height of the prism

The formula for the area of the base of the prism depends upon the shape

of the base.

Rectangular Prism A H
