If you feel comfortable with the concepts covered in the questions, move forward to Discover. If you experienced difficulties or want more practice, use the resources in Refresher to review these important concepts before continuing through the lesson or contact your teacher.

Refresher

The interactive applet titled “Exploring Surface Area, Volume, and Nets—Use It” can help you review many aspects of surface area and volume. You will find the interactive piece on the right-hand side of the website.

Select the “Use It” tab at the bottom of the activity to review the nets of all of the 3-D objects that were previously explored. The activity tests your ability to visualize the net of a given 3-D object.

Select the “Explore It” tab to review the surface area and volume formulas for all of the 3-D objects previously introduced. This applet also enables you to do a side-by-side comparison of two formulas. For example, you can use this feature to compare

  • the surface area formula of a sphere and the volume formula for a sphere
  • the volume formulas of a cylinder and a cone

You can also access a video that demonstrates how math is used in designing large inflatable shapes. On the left-hand side of the website, choose “Exploring Surface Area and Volume (Video Interactive)” to view the video.
