Instructional Ideas

• Ask class members to create composite solids and swap with a classmate to calculate the volume

Classroom Considerations

• Assumes pupils already know the surface area and volume formulas for 3-D shapes
• Expects individuals know the Pythagorean Theorem

• This video is hosted on YouTube

Pros

• Reviews the surface area and volume formulas for solids
• Links to practice problems and more videos with composite solids

Cons

• None
