Stop the rotation. Look at each of the polyhedra. Instead of using the stop button you can also try dragging the mouse on the figures to rotate them. Click on the pull down menu with choices color model, light model, metal model, wire model and select wire model and view the cube. Now change to the other four polyhedra and count the edges and vertices for all of them.
Crystals are real world examples of polyhedra.
The salt you sprinkle on your food is a crystal in the shape of a cube. Another interesting polyhedral shape is the truncated icosahedron. It is not a regular polyhedron, but it is extremely important in the world of science. Carbon-60, also known as the buckyball, takes the shape of a truncated icosahedron. There's lots to learn about crystals and buckyballs .
