Unit 7, Lesson 21# Volume of Composite Solids

EngageNY 45 min(s)

Students find the volumes of figures composed of combinations of cylinders, cones, and spheres. Students should know that volumes can be added as long as the solids touch only on the boundaries of their figures. Then, allow them to work independently or in pairs to determine the volumes of composite solids in Exercises. All of the exercises include MP.1, where students persevere with some challenging problems and compare solution methods, where students explain how the structure of their expressions relate to the diagrams from which they were created.
