This is an illustration showing three cubes. There are no units of measurement: Cube A is a 1 by 1 by 1 cube; Cube B is a 2 by 2 by 2 cube; and Cube C is a 3 by 3 by 3 cube. Underneath Cube A is written ‘side = 1’, ‘surface = 6’, ‘volume = 1’ and ‘surface/volume = 6’. Underneath Cube B is written ‘side = 2’, ‘surface = 2 squared times 6 = 24’, ‘volume = 2 cubed = 8’ and ‘surface/volume = 3’. Underneath Cube C is written ‘side = 3’, ‘surface = 3 squared times 6 = 54’, ‘volume = 3 cubed = 27’ and ‘surface/volume = 2’. This illustration shows a cube with sides of 1 unit length, next to cubes with sides of 2 and 3 unit lengths. Underneath each cube are measurements of ‘side’, ‘surface’, ‘volume’ and ‘surface/volume’.
