What are two ways to calculate volume?

Answer 1

It depends what 3D figure you are trying to determine the volume for. There are different volume formulas for different figures.

For example, the volume formula for a cube is V=s3 where s is the side.

Volume formula for a rectangular prism is V=length x width x height.

For a cyclinder it's V= Pi x radius2 x height

For a cone it's V=(Pi x radius2 x height) / 3

Most volume formulas are contained on what may be called a reference sheet inside almost every math textbook.
