A rectangular prism is a polyhedron with bases made of rectangles connecting each other. Since a cube has two rectangles connected each side, it's a rectangular prism.Polyhedra are named after the great philosopher, Plato. This is why the regular polyhedra are called Platonic solids. He linked each shape to the elements of fire, earth, wind and water. He thought that the cube was linked to earth, the tetrahedron to fire, and the polyhedra with triangle faces to water. Perhaps most interestingly, he linked ...Cubes and pyramids are examples of convex polyhedra.
