Volume of a Rectangular Solid

Volume of Rectangular Solid = length x width x height

Example

Find the volume of the figure shown below

Volume = 6 x 4 x 3 = 72

Multiplying the length, width, and height yields the volume of the rectangular solid. This formula applies to cubes as well, another very common rectangular solid tested on the GMAT.
