Volume of a Cube Calculator
This Volume of a Cube Calculator helps you find the space inside a cube when the side length is known. It uses the formula V = a³, where a is the side length and the answer is written in cubic units. Multiply the side length by itself three times to get the volume. It is a simple way to check answers, understand the cube volume formula, and practise basic geometry step by step.
In the diagram, each edge is labeled a.
Step-by-step method
- Identify what is given.
- Write the formula.
- Substitute the value and calculate the volume.
Formula:
Example 1: a = 4
Step 1 - Identify what is given.
In this problem: The given side length is a = 4.
Step 2 - Write the formula.
In this problem: Use the cube volume formula: V = a³.
Step 3 - Substitute the value and calculate the volume.
In this problem: Substitute a = 4: V = 4³ = 64.
Final answer: V = 64
Example 2: a = 2.5
Step 1 - Identify what is given.
In this problem: The given side length is a = 2.5.
Step 2 - Write the formula.
In this problem: Use the cube volume formula: V = a³.
Step 3 - Substitute the value and calculate the volume.
In this problem: Substitute a = 2.5: V = 2.5³ = 15.625.
Final answer: V = 15.625
