The fifth and final regular polyhedron is the dodecahedron, with 12 pentagonal faces.

And what shall we say of the infinite variety of those exquisite and regular polyhedrons in which the world of crystals is so rich?
1
Five Platonic solids: tetrahedron, cube, octahedron, dodecahedron, icosahedron.
2
Are not the five platonic solids, of which Plato had so much to say, just various crystalline forms?

It was a perfect evocation of the ghostly quality of "surgical" Cold War combat: We fight amongst Platonic solids!

The highlight of the 13th and final book of Euclid's Elements was the proof that there are just five " Platonic solids".

Suppose, for example, that we attempt to deal decoratively which such simple figures as the three lowest Platonic solids-thetetrahedron, the hexahedron, and the octahedron.
