Volume of Cube
The volume of a cube is a measure of the three-dimensional space it occupies (e.g., how much water it could hold). A cube is a special type of rectangular prism where all its sides (length, width, and height) are equal in length.
Formula for the Volume of a Cube
The formula for the volume (V) of a cube is
V = s3, where s is the length of the side.
The following diagram shows the formula to find the volume of a cube. Scroll down the page for more examples and solutions on how to find the volume of a cube.
How to Calculate the Volume of a Cube
- Find the length of one side (s): This measurement should be given to you.
- Cube the side length: Multiply the side length by itself three times (s×s×s).
- Include Units: The volume will always be in “cubic units”
Example
Find the volume of a cube with a side length of 5 cm.
Side length (s): 5cm
Cube the side length: V=(5cm)3
Calculate: V=5×5×5 cm3 = 25 cm3
Tips to remember
“Volume is cubed, area is squared.”
