Unit 6, Lesson 23# Surface Area: 3D

EngageNY 45 min(s)

Students determine the surface area of three-dimensional figures, including both composite figures and those missing sections. Explain the process you used to determine the surface area of the pyramid. The surface area of a pyramid is the union of its base region and all its lateral faces. Encourage students that are struggling to draw a net of the figure to help them determine the surface area. Students find the surface area of the rectangular prism.
