What's in a cube: level 2

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.
