The regular and symmetrical nature of a platonic solid also means that it is relatively straightforward to find its surface area or volume. This section contains separate pages that explore the characteristics of the regular hexahedron (or cube) and the tetrahedron (including the regular tetrahedron), including details of how to calculate the surface area and volume for these shapes.

Regular platonic solids

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.

A polygon is regular if it is uniform and its faces are all alike. The regular convex polyhedra are the five Platonic solids, which have been known since classical Greece. The ancient Greek mathematician Euclid proved in his Elements of Geometry that there are only five Platonic solids – the

Platonic solids, as ideas and concepts, have been with us ever since Plato decided to tell an origin story of the universe. Plato's universe originated with a master craftsman, a demiurge, that created the essential elements that make up reality, ourselves included: "[T]he Craftsman begins by fashioning each of the four kinds “to be as… The dodecahedron is the only platonic solid with a face in the shape of a pentagon. The tetrahedron, cube, and octahedron are seen in crystal structures.

Another virtue of regularity is that the Platonic solids all possess three concentric spheres: the circumscribed sphere that passes through all the vertices, the midsphere that is tangent to each edge at the midpoint of the edge, and the inscribed sphere that is tangent to each face at the center of
