Volume formula for cube: V = a3. Volume of a cube is equal to side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. Thermal Engineering

## What is Volume

**Volume** is a basic **physical quantity**. **Volume** is a derived quantity and it expresses the **three dimensional extent** of an **object**. Volume is often quantified numerically using the SI derived unit, the **cubic metre**. For example, the volume inside a **sphere** (that is the volume of a ball) is derived to be** V = 4/3πr**^{3}, where r is the radius of the sphere. As another example, volume of a cube is equal to side times side times side. Since each side of a square is the same, it can simply be the length of one side **cubed**.

If a square has one side of 3 metres, the volume would be 3 metres times 3 metres times 3 metres, or 27 cubic metres.
