Because space is three dimensional (it has length, width and height) we use cubic units to measure volume. In the metric system the main units of volume are:
• cubic millimetres
• cubic centimetres
• cubic metres
• a litre is also a metric measure of volume, which is the space taken by a 10 cm by 10cm by 10cm container.
A cubic millimetre is incredibly tiny, each side being just a millimetre in length. Each side of a cubic centimetre is 1 cm long. A cubic metre can be made out of canes or one metre rulers and it surprising how children like to sit inside the final cube!
All our volume worksheets together with many others can be found in the Year 6 measurement category.
