Calculating the Volume of a Rectangular Prism:
This formula can be used to calculate to volume of a rectangular prism with known measurements for all three sides:
Typically the various sides of this three dimensional shape are labelled a, b and c. If you prefer you can think of these as the width, height and depth. By multiplying all three side lengths together you have the volume of the three dimensional shape.
Below is an example of how to find the volume if three side lengths are known. In the example the rectangular prism is 5 units wide, 2 units tall and 4 units deep:
