Lesson 4: Volume of Prisms Definitions Volume – is the measure of space it occupies. Polyhedron – 3 dimensional figure with faces that are polygons. Prism - solid figure that has two parallel and congruent bases that are polygons. *** They are named by the shape of their base.

Lesson 4: Volume of Prisms Faces are the flat surfaces in the shapes of polygons. Edges are line segments that join two vertices. Vertex is a point where two or more straight lines meet. *** Cones, cylinders and spheres are not polyhedrons b/c they have curved sides and are not polygons. They have no faces, vertices and edges.
