The Platonic Solids

explanation dodecahedron octahededron hexahedron (cube) tetrahedon icosahedon ø Midsphere Diameter

All five so-called Platonic Solids. The Platonic Solids are the five regular convex polyhedra. The Cube is the most famous one, of course, although he likes to be called “hexahedron” among friends. Also the other platonic solids are named after the number of faces (or hedra) they have. I.e. Tetrahedron, Octahedron, Dodecahedron, Icosahedron. (Now you know how to count in classical Greek, too!) There is only parameter:the diameter of the midsphere. The midsphere is the sphere from the center of the object that touches all the edges exactly in middle.
