In this activity, you will be challenged to work out **volume** and **area** of different shapes.

**Volume**

Remember, volume is measured in cubic units, e.g. **1 cm³** or **1m³.**

We need to know the following formulae to work out the** volumes **of these 3D solid shapes.

**Cube**

You must know the side length.

Remember, the **length,** the **width** and the **height **will all be **equal** to the side length because this is a **cube.**

Volume of **cube **= side length x side length x side length.

**Cuboid**

You must know:

**The length**

**The width**

**The height**

Volume of **cuboid** = length x width x height

**Area**

Remember area is measured in square units for example, **m² or cm².**

**Rectangles**

You must know:

The **base** length.

The perpendicular **height **from the base to the top.

Area of **rectangle **= base x height.

**Parallelogram**

You must know:

The **base **length

The perpendicular **height** from base to top (not the slant height)

Area of **parallelogram** = base x height

**Triangle**

You must know,

The **base** length

The perpendicular **height** from the base to the apex (not the slant heights)

Area of **triangle** = 1/2 base x height

Or

Area of **triangle** = base x height ÷ 2
