Enter the room length (ft), the room width (ft), and the room height (ft) into the Room Volume Calculator. The calculator will evaluate and display the Room Volume. 

Room Volume Formula

The following formula is used to calculate the Room Volume. 

RV = RL * RW * RH
  • Where RV is the Room Volume (ft^3)
  • RL is the room length (ft) 
  • RW is the room width (ft) 
  • RH is the room height (ft) 

To calculate the room volume, multiply the room length, width, and height.

How to Calculate Room Volume?

The following example problems outline how to calculate Room Volume.

Example Problem #1

  1. First, determine the room length (ft).
    1. The room length (ft) is given as 12.
  2. Next, determine the room width (ft).
    1. The room width (ft) is calculated as: 10.
  3. Next, determine the room height (ft).
    1. The room height (ft) is found to be: 8.
  4. Finally, calculate the Room Volume using the formula above: 

RV = RL * RW * RH

Inserting the values from above yields: 

RV = 12 * 10 * 8 = 960 (ft^3)

Example Problem #2

The variables needed for this problem are provided below:

room length (ft) = 20

room width (ft) = 30

room height (ft) = 8

Entering these values and solving gives:

RV = 20 * 30 * 8 = 4,800 (ft^3)
