Solids are figures having the three dimensions of length, width, and depth
bounded by plane surfaces. Solids may also be known as polyhedra. The
plane surfaces of polyhedra are called faces and if the faces are regular
polygons, the solids are regular polyhedra.
Figure 2-10 shows regular polyhedra or solids.
