Platonic Solids or Shapes are any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. There are only 5 Platonic Solids.
According to Plato c. 360 B.C, each solid corresponds to a specific element. The tetrahedron corresponds to fire; the cube corresponds to earth; the octahedron corresponds to air; the dodecahedron corresponds to ether and the icosahedron corresponds to water. You can read more here.
Tetrahedon - Fire Element
Also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.
Cube - Earth Element
Hexahedron or Cube. 6 faces, each face is the same-sized square; 3 squares meet at each corner
Octahedron - Air Element
An octahedron is a polyhedron with 8 faces, 12 edges, and 6 vertices and at each vertex 4 edges meet.
Dodecahedron - Ether Element
A dodecahedron is a three-dimensional figure having twelve faces that are pentagonal in shape. It has 12 faces, 20 vertices, and 30 edges
Icosahedron - Water Element
A regular icosahedron is a convex polyhedron with 20 faces, 30 edges and 12 vertices
