**VOLUME OF A RECTANGULAR PRISM**

A rectangular prism is a box-shaped object with six sides. Some of the examples in real life are: a mail box, a shoe box, a juice box etc.

V = LWH

Example:

Calculate the volume of a rectangular prism that measures 6 feet long, 3 feet wide and 2 feet high.

V = LWH = 6×3×2 = 36

The volume of the rectangular prism is 36 ft^{3}

In your trades books the word “altitude” (A) may be used instead of height (H).

The formula then looks like this:

V = LWA

The problem with altitude (A) is that the word “area” is also abbreviated as (A)

To avoid confusion, the word altitude is not used on this site, only in aviation context.

**VOLUME OF A CUBE** V = s

^{3}

Example:

Calculate the volume of a cube that measures 7 cm.

V = s^{3} = 7^{3} = 343

The volume of the cube is 343 cm^{3}
