What Is the Formula for Cubic Inches?

Cubic inches are the expression of the volume of a three-dimensional object. For typical square or rectangular areas, multiple the length of each side in inches, according to Math.com.

  1. Measure each side

    A three-dimensional object has three sides -- often referred to as the object's length, width and depth. Use a ruler to measure each side in inches.

  2. Multiply the three lengths

    For a square, all three sides are the same. If a rectangular area has sides of 7 inches, 4 inches and 10 inches, multiply these together. The answer is 280.

  3. Record the result

    The answer of 280 is recorded as 280 cubic inches.
