wikiHow Calculating the Volume of a Box Calculator To calculate the volume of a box, you need to know the dimensions of the box. The volume of a box is the amount of space inside the box, measured in cubic units. Here are the steps to calculate the volume of a box: 1. Measure the length of the box in units (e.g., inches, feet, meters). 2. Measure the width of the box in the same units. 3. Measure the height of the box in the same units. 4. Multiply the length by the width by the height to get the volume of the box. The formula for calculating the volume of a box is: Volume = Length x Width x Height For example, if you have a box with a length of 10 inches, a width of 5 inches, and a height of 3 inches, you would calculate the volume as follows: Volume = 10 inches x 5 inches x 3 inches Volume = 150 cubic inches So the volume of the box is 150 cubic inches.
