The existence of only 5 platonic solids can be proved using Euler’s formula. It is written as: F + V – E = 2, here F = number of faces, V = number of vertices, and E = number of edges. Suppose we substitute the number of faces, edges, and vertices of any platonic solid in the above formula.a Platonic solid by cutting along its edges, we always obtain a flat nonoverlapping simple polygon. We also give self-overlapping general unfoldings of Platonic solids other than the tetrahedron (i.e., a cube, an octahedron, a dodecahedron, and an icosahedron), and edge unfoldings of some Archimedean solids: aThe faces on each one are regular polygons, which means all angles and edges are congruent. The same number of faces on each one meet at each vertex. Each of the shapes can fit evenly into a sphere. The five platonic solids are the: 1. Tetrahedron - 4 faces. 2. Cube, or hexahedron - 6 faces.This video describes why there are only 5 platonic solids in 3 dimensions: using a construction algorithm that starts with some regular polygons sharing edges in the plane, and then bending along the edges into the third dimension to "close" the solid, we can only get so many solids before we can't close or fit all the polygons in the plane.. But in non-Euclidean geometry, regular polygons ...

Exploding Solids! Now, imagine we pull a solid apart, cutting each face free. We get all these little flat shapes. And there are twice as many edges (because we cut along each edge).

A six sided die is the shape of a cube.If the cube has side lengths of 1, then its dual the octahedron will have edge lengths of √2. This is because the octahedron's edges are the diagonals of the cubes faces. Recall, that the diagonal of a square with side lengths of 1 is √2. The Sum of the angles of the Cube is 2160°. (90 x 4) = 360; 360 x 6 = 2160.
