Frequently Asked Questions
What is the volume of a cube?
The volume of a cube is the amount of space it occupies. Because all three dimensions are equal, the formula is simply V = s³, where s is the side length.
What units does this calculator use?
This calculator is unit-agnostic. If you enter the side in meters, the result is in cubic meters (m³). Use whatever unit matches your measurements.
How is a cube different from a cuboid?
A cube has all three dimensions equal (length = width = height). A cuboid (rectangular prism) can have any three different dimensions. The cube formula V = s³ is a special case of the cuboid formula V = l × w × h. Use our cuboid volume calculator when the dimensions differ.
What is the surface area of a cube?
A cube has 6 identical square faces, so the surface area is SA = 6 × s². For example, a cube with a 5 cm side has a surface area of 6 × 25 = 150 cm².
How do I find the side length if I know the volume?
Take the cube root of the volume: s = V^(1/3). For example, if the volume is 27 cm³, the side length is the cube root of 27 = 3 cm.
Can I share my calculation?
Yes. After clicking Calculate, the URL updates with your input value. Copy and share the URL to let anyone else see the same pre-filled form and result.
