Calculate the volume of a cube by entering the length of one side. A cube is a 3D shape with all sides of equal length.
Formula:
V = a³
Where:
- a = Length of a side of the cube

About Cube Volume
A cube is a three-dimensional shape with 6 square faces, 12 edges, and 8 vertices. All edges of a cube have the same length.
The volume of a cube is calculated by cubing the length of one side (raising it to the power of 3). This gives us the formula V = a³, where a is the side length.
For example, if the side length of a cube is 5 cm, its volume would be 5³ = 5 × 5 × 5 = 125 cm³.
How to Calculate Cube Volume
Step 1: Measure the Side Length
Measure any side of the cube. Since all sides of a cube are equal, you only need to measure one. Make sure your measurement is accurate for the best results.
Step 2: Cube the Side Length
Once you have the side length, cube it by multiplying it by itself three times (or raising it to the power of 3). For example, if your side length is 4 cm: 4³ = 4 × 4 × 4 = 64 cm³.
Step 3: Add the Unit
The result will be in cubic units. If you measured in centimeters, your result will be in cubic centimeters (cm³). If you measured in inches, your result will be in cubic inches (in³), and so on.

Tips and Common Mistakes
- Measurement Consistency: Always measure all dimensions in the same unit system. Mixing units will lead to incorrect results.
- Cubing vs. Multiplying by 3: Remember that cubing (raising to power 3) is different from multiplying by 3. A common mistake is calculating 3 × a instead of a³.
- Perfect Cubes: In real-world applications, few objects are perfect cubes. For slightly irregular shapes, measure all sides and use the rectangular prism formula instead.
- Significant Digits: For practical purposes, maintain appropriate precision in your measurements and final result.
Frequently Asked Questions
A cube is a special type of rectangular prism where all sides have the same length. It has 6 square faces, 12 edges, and 8 vertices, with all edges meeting at 90° angles. Other 3D shapes like spheres, cylinders, and pyramids have different geometric properties. The cube is distinctive because its regular structure makes its volume calculation particularly simple - just the side length cubed (a³).
Tips
- Enter the dimensions in the same unit for consistency.
- Results update automatically as you type.
- Use the unit selector to convert between different measurement systems.
