Volume of a Box

This is an important calculation for all electricians to understand. The volume of a box is the result of multiplying the length of each side times the depth of the box. So with a box that is 6 inches by 8 inches by 4 inches deep, the calculation would be 6 inches times 8 inches times 4 inches. Result 192 cubic inches.

Cubic inches are calculated for boxes expected to enclose conductors size #6 AWG and smaller.
