About This Chapter

The Washington Educator Skills Test (WEST) is now the National Evaluation Series examination. Review the properties of geometric solids in this chapter, then earn an addition to your Washington state teaching certificate by passing the test.

WEST Math: Geometric Solids - Chapter Summary

In preparation for taking the WEST Math examination, utilize this chapter's online video lessons. Review what you know about geometric solids and learn some concepts that may be unfamiliar to you. For example, you can re-examine the rules for calculating the area of basic geometric solids, and illustrate various geometric shapes. The video lessons in this chapter could help you to:

  • Describe planes and polyhedrons
  • Calculate the volume of 2D and 3D shapes
  • Define and find the surface volume of prisms, pyramids and cylinders
  • Measure and write the formulas for the surface areas of a cone and a sphere

Use these video lessons to refresh your memory as you get ready to take the WEST Math examination. The lessons are fun as well as educational, and they're presented by knowledgeable teachers. You can study at a pace that suits your schedule and submit your questions on geometric solids. The video lessons are accompanied by text transcripts that you can study if you prefer. Self-assessment quizzes and a chapter examination will test your retention of these concepts.

How to Calculate the Volumes of Basic Shapes

2. How to Calculate the Volumes of Basic Shapes

Squares pegs = square holes. Triangular pegs = triangular holes. But where does a sphere go? In this lesson, review volumes of common shapes while contrasting a sphere and a cylinder - after all, they both go into the circular hole... right?

Prisms: Definition, Area & Volume

3. Prisms: Definition, Area & Volume

Watch this video lesson and you will see that there are different kinds of prisms. You will also learn how to separate a prism into its various parts so you can easily find the surface area. You will also learn the formula for the volume.

Pyramids: Definition, Area & Volume

4. Pyramids: Definition, Area & Volume

Do you think of the great pyramids of Egypt when you hear the word pyramids? Watch this video lesson to learn why they are called pyramids and also how to find their surface area and volume.

What Are Cylinders? - Definition, Area & Volume

5. What Are Cylinders? - Definition, Area & Volume

Watch this video lesson to learn why soda cans are cylinders and the method by which you can discover how much soda can fit inside by finding the volume. You will also learn about finding a cylinder's surface area.

Cones: Definition, Area & Volume

6. Cones: Definition, Area & Volume

Watch this video lesson to learn where in the real world you will see cones. Also, you will learn the formulas for finding the surface area and volume of these cones.

Spheres: Definition, Area & Volume
