Volume of a box calculator

The following volume of a box calculator will help you find the volume for any box when the length, the width, and the height are given. Recall that a box is also called rectangular prism.

Guidelines to follow when using the volume of a box calculator

Just enter the length, the width, and the height of the box and hit the calculate button.

Recall that the formula to get the volume of a rectangular box is

V = l × w × h

l is the length

w is the width

h is the height

Therefore, the volume depends on the size of l, w, and h . So just enter the size of l, w, and h in the calculator to get the volume.

The calculator will only accept positive value for the length, the width, and the height since a distance cannot be negative. If you enter a negative number, it will prompt you to enter a valid number.

Enter the length, width and height without the unit. For example, if your length is 2 cm, enter 2.

Then, just put cm³ or cubic centimeter next to the answer

Examples showing how to use the volume of a box calculator to find the volume of some rectangular solids

Example #1:

Find the volume of a waterbed king-size mattress that is 7 ft by 6 ft by 1 ft. 

Enter 7 in the box that labeled 'Enter the length of the box'

Enter 6 in the box that labeled 'Enter the width of the box'

Enter 1 in the box that labeled 'Enter the height of the box'

Hit the button labeled 'Calculate'

The calculator will display 42, so the volume of the mattress is 42 ft³ or 42 cubic feet.

Example #2:

The main tank at an aquarium is shaped like a rectangular prism with a length of 40 feet, a width of 25 feet and a height of 9 feet. What is the volume of the aquarium?

Enter 40 in the box that labeled 'Enter the length of the box'

Enter 25 in the box that labeled 'Enter the width of the box'

Enter 9 in the box that labeled 'Enter the height of the box'

Hit the button labeled 'Calculate'

The calculator will display 9000, so the volume of the aquarium is 9000 ft³ or 9000 cu ft.

Example #3:

A cargo trailer is shaped like a rectangular prism with a length of 14 meters, a width of 2.5 meters and a height of 3.5 meters. What is the volume of the trailer?

Enter 14 in the box that labeled 'Enter the length of the box'

Enter 2.5 in the box that labeled 'Enter the width of the box'

Enter 3.5 in the box that labeled 'Enter the height of the box'

Hit the button labeled 'Calculate'

The calculator will display 122.5, so the volume of the aquarium is 122.5 m³ or 122.5 cubic meters.
