Learning objects Working it out!


See how small a cubic centimetre looks when compared with a cubic metre (100 cm x 100 cm x 100 cm). Then estimate the volume of cuboids, such as a packet of food and a tool box. Rotate a 3D grid to help you work out dimensions in centimetres. First work out the area of the base. Then multiply your answer by the height to get the volume. Use a 3D animation of each estimate to improve your answer. Fill in data tables by working out progressive totals of length, width, height and volume (up to one cubic metre). This learning object is one in a series of five objects.

Educational details

Key learning objectives
  • Students use the strategy of guess, check and improve to estimate the volume of irregular everyday objects.
  • Students apply the formula, area of base x height, to calculate the volume of everyday objects.
  • Students complete data tables concerning the volume of everyday objects.
Educational value
  • This resource is useful for the Australian Curriculum content description in year 8 mathematics about using a formula to find the volume of rectangular prisms with formal units.
  • It may also be relevant in supporting students in year 9 to develop the formula for volumes of rectangular prisms .
