How to Find Cubic Feet

Step-by-Step Guide

1. 1

   Step 1: Measure the length of the object.

   If it doesn’t measure well into whole feet, feel free to measure it in inches for now.
   
   Ex. 8 inches (20.3 cm).
2. 2

   Step 2: Measure the width of the object.

   If you measured the length in inches instead of feet, be sure to do the same with the width to stay consistent.
   
   Ex. 16 inches (40.6 cm). , This gives the two-dimensional area of the base of the object.
   
   Ex. 8 inches (20.3 cm) x 16 inches (40.6 cm) = 128 square inches. , Write down this number.
   
   Ex. 27 inches (68.6 cm). , This gives you a three-dimensional, or cubic, measurement.
   
   Ex: 128 square inches x 27 inches (68.6 cm) = 3456 cubic inches. , To convert from cubic inches to cubic feet, divide the result by
   1728.
   
   Ex. 3456 cubic inches / 1728 = 2 cubic feet.

   Step 3: Multiply the length by the width.

4. 4

   Step 4: Measure the height of the object.

5. 5

   Step 5: Multiply the two-dimensional area of the base by the height.

6. 6

   Step 6: Convert to cubic feet if necessary.
