Use Area and Volume Formulae

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
