The term 'Six Faces, Solid Figure of' is a reference to a HEXAHEDRON, which is a three-dimensional shape with six faces. It is also known as a cube, since it has the same number of faces and edges. A HEXAHEDRON is a regular polyhedron, meaning that all of its faces are congruent and all of its angles are equal. It is one of the five Platonic solids, which are the only convex polyhedra that have the same number of faces meeting at each vertex.
