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

**Volume**

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

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

**Cube**

We need to 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**

We need to know the length, the width and the height

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

**Area**

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

**Rectangles**

We need to know the base length and the perpendicular height from the base to the top.

**Area of rectangle = base x height**

**Parallelogram**

We need to know the base length and the perpendicular height from base to top (not the slant height)

**Area of parallelogram = base x height**

**Triangle**

We need to know the base length and the perpendicular height from the base to the apex (not the slant height)

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

Or

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

That's a lot to remember! You can look back at this page at any point by clicking on the red help button on the screen.
