The volumes and surface areas of certain simple objects such as cubes and prisms can be calculated using formulae.

The surface area of an object is the total area of the outside surfaces of the object.

### Units of Volume

- The basic unit for volume is the cubic metre, written m
^{3}. - 1 cubic metre is the volume occupied by a cube of length 1 metre.
- Smaller volumes are often measured in cubic centimetres, cm
^{3}, sometimes called cc. - 1 litre = 1000 cm
^{3}

1 mL = 1 cm^{3}(1 cc)

### Volume and surface area formulae

Only the cube and cuboid formulae need to be memorised.
