Volume of a Cube
A cube has all sides the same length Volume = length × length × length Or we can write: Volume = side³ Example: If each side is 3cm, volume = 3 × 3 × 3 = 27 cubic cm
Volume of a Cuboid
A cuboid has rectangular faces Volume = length × width × height The three measurements can be different Example: 4cm × 2cm × 3cm = 24 cubic cm
