Whats a tetrahedron?
... And whats the volume of a cube? You can explain questions like these by using the geometric elements with a volume. Each of the different objects can be opened on one side for experimenting. In this way kids can, for instance, compare the various cubic capacities by means of liquids. The coloured PE films with a thickness of 2 mm are intended for removing and unfolding in order to illustrate the bases of the objects.
