7.1

The surface area, S, and volume, V, of a right rectangle prism with length L, width, W, and height H are =2Lw+2wh+2Lh or **V**= Lwh The surface area, S, and Volume, V, of a cube with side s are =6² V= s³

7.2 =L+2B or **S** hp+2B= = __Cavalieri's Principle__ If two solids have equal heights and the cross sections formed by every plane parallel to the bases of both solids have equal areas, then the two solids have equal volumes. **__Volume of a Prism__** The volume V, of a prism with height h and base area B is **V**= Bh 7.3 **Pyramids:** polyhedron consisting of a base, and three or more lateral faces. **Base**: bottom of something **Lateral Faces:** how many faces that you can see. Vertex of the Pyramid:** The lateral faces are triangles that share a single vertex. **Base Edge:** Each lateral face has one edge in common with the base. Height:** the lengh of an altitude
 * Altitude:** a segment that has endpoints in the planes containing the bases and that is perpendictual to both planes.
 * Height:** the length of an altitude
 * Surface Area of a Right Prism:** Surface area S, of a right prism with lateral area L, base area B, perimeter p, and height h is
