Cube (Thirds) Dissection: Three Congruent Pyramid Combos

The cube can be dissected into 6 congruent square pyramids, which all meet at the center of the cube at a dihedral angle of 45 degrees. Two adjacent pyramids can be combined for a third-cube. It is simple and playful, worth a place in an elementary teacher’ resource kit. Please check out numerous other ways to dissect a cube!
