Unit 6, Lesson 24# Surface Area: 3D (Continued)

EngageNY 45 min(s)

Students determine the surface area of three-dimensional figures-those that are composite figures and those that have missing sections. Students continue to work on surface area advancing to figures with missing sections. Students determine the surface area of each prism separately and added them together. If all three prisms were separate, would the sum of their surface areas be the same as the surface area you determined in this example?
