Polyhedra and Prisms

Polyhedra and Prisms

Polyhedra and Prisms. Definitions. A polyhedron is a solid, bounded by polygons (called faces), that enclose a (single) volume, or region of space. An edge is a line formed by the intersection of 2 faces. A vertex is a point where 3 or more edges come together.
