Learning objects What's in a cube: level 2

TLF ID L166

Watch a demonstration of the size of a cubic metre (100cm x 100cm x 100cm). See how small a cubic centimetre looks when compared with a cubic metre. Estimate the volume of irregular cuboid objects such as a small kennel, toy train, and backpack. Rotate a 3D grid to help you work out dimensions in centimetres. Estimate the relative volume of the different items. First, estimate the regular part of the shape. Then, estimate the irregular parts and add up the total number of cubic centimetres that make up the item. Use a 3D animation of each estimate to improve your answer. 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.
Educational value
  • This resource is useful for the Australian Curriculum content description in 7 about calculating volumes of rectangular prisms.
  • It may also be relevant in supporting students in year 8 to use formulas to solve problems involving volume.
Year level

7; 8
