Cube (Hexahedron)The cube (or hexahedron) is one of the five Platonic solids. It is composed of 6 squares linked together at right angles. For a cube with edge length a the volume V = a^{3}, its surface S = 6a^{2}. The radii of the circumscribed (r_{c}) and inscribed (r_{i}) spheres are r_{c} = a/2 and r_{i} = a/2.
