This lesson focuses on the computation of volumes and surface areas for various geometric solids including prisms, pyramids, cylinders, cones, and spheres. Students will memorize key formulas for calculating volumes and surface areas of prisms, pyramids, and cylinders. The lesson also introduces terms such as concave, convex, regular, and nonregular solids, as well as the concept of Platonic solids and cross-sections. For homework, students are assigned problems from page 798 to reinforce their understanding.
