The Power of Two Cube consists of a dissected cube in seven pieces painted yellow, green and white.  The material demonstrates how a shape or a unit can be divided or combined to create a new form.  For example, the large yellow cube is half the size of the large white prism, but twice the size of the smaller green prism.  The completed cube is 8 cm per side and comes in a box with two hinged sides and a lid.  This set makes an excellent companion to the Power of Three Cube as well as the Binomial Cube and the Trinomial Cube.
