Introduction

Solid Geometry is the geometry of three-dimensional spaces. It is often called three dimensional because solid objects have length, width, and height.

Solids also have other properties such as volume and surface area. In this lesson, you will learn about different types of solid objects and how to calculate their properties.

In this lesson, you will begin exploration of solid (3-deminsional) figures.

  1. Go to NCTM Illuminations: Geometric Solids to learn more about 3–dimensional solids.
  2. Select a shape from the dropdown menu in the activity.
  3. Manipulate the shape and try to identify all of the faces, edges, and vertices. Be sure to select Show Total so that you know when you have found all of the objects.
  4. As you work through each shape in the dropdown menu, complete 11.01 3D Shapes Explore.
  5. Submit your completed work to the 11.01 3D Shapes Explore Dropbox. You may also want to use it as you go through the lesson.
