# Ch 24: Polyhedrons & Geometric Solids

With the help of the online video lessons in this chapter, elementary school students can learn about the characteristics and different kinds of polyhedrons and geometric solids. Each lesson is accompanied by a short practice quiz.

## Polyhedrons & Geometric Solids - Chapter Summary

Through the video lessons in the Polyhedrons & Geometric Solids chapter, you can increase your elementary school students' understanding of the area and volume of pyramids, cones, prisms and cylinders. Students can also learn to count the edges and vertices of polyhedrons. After students complete the last quiz, they can take the chapter exam.
