TLF ID L160
Help three cuboid characters estimate and compare the volumes of cube-shaped rocks made by a special volcano in 'Cubiland'. Each character uses a different measuring unit: small, medium-sized or large. Notice that if 8 medium cubes and 27 small cubes fill a large cube that this ratio can be applied to all 'cubirocks'. Use a measuring cube to help estimate the volume of different 'cubirocks' made up of cubes. Volumes range from 1 unit up to 162 units (3x3x3x6). Notice that the volume of a cube stays the same when its parts are rearranged. This learning object is one in a series of three objects.
