#4. Icosahedron (20 equilateral triangle faces, 12 vertices, 30 edges)
30cm/12" in diameter
Since ancient times mathematicians have known of the existence of five three-dimensional shapes which have come to be called Platonic Solids. Each face is the same regular polygon, and the same number of polygons meet at each vertex.
