The formula for the volume of a rectangular prism is:

Volume=1/3 (Area of base) (height)

The area of base is calculated using the formula:

Area=bh/3

Where:

b=base

and

h=height

Volume=1/3 (Area of base) (height)

The area of base is calculated using the formula:

Area=bh/3

Where:

b=base

and

h=height
