A Platonic solid is a polyhedron, or 3 dimensional figure, in which all faces are congruent regular polygons such that the same number of faces meet at each vertex. There are five such solids: the cube (regular hexahedron ), the regular tetrahedron, the regular octahedron, the regular dodecahedron, and the regular icosahedron.

The Platonic solids are a special group of 3D objects with faces that are congruent, regular polygons. The name of each Platonic solid comes from the number in Greek for the total number of faces it has, and "hedron", which means "face". Tetrahedron: An object with four congruent faces. Each face is an equilateral triangle.Yes! The cube is one of the five platonic solids, alongside the octahedron, tetrahedron, icosahedron and dodecahedron. It is the only 6-sided shape among them and consists of 8 vertices (corners), 12 edges that form squares on all 6 sides, and 6 faces. This makes it the most common of all platonic solids.Platonic solids rolling through their edge MN withdifferent rotation angles shown in Table 2.

We developed a path-planning algorithm based on the breadth-first-search algorithm that generates a ...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). Example: the cut-up-cube is now six little squares. And each square has 4 edges, making a total of 24 edges (versus 12 edges when joined up to make a cube).Platonic solid. In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons (all angles congruent and all edges congruent), and the same number of faces meet at each vertex.
