Students will understand that:

• The surface area of a composite object can be found by determining the sum of the surface area of each individual object and subtracting the area of overlap.

Essential Questions:

What is a composite object? What is overlap?

What is a right cylinder? What is a triangular prism?

General Outcomes:

• Students will describe the characteristics of 3D objects and 2D shapes, and analyze the relationships among them.
• Students will determine the surface area of a composite 3D object to solve problems.
