Unit 6, Lesson 16

Slicing a Right Rectangular Prism with a Plane

EngageNY 45 min(s)

Students describe rectangular regions that result from slicing a right rectangular prism by a plane perpendicular to one of the faces. Students examine the cross sections of solid figures in the next four lessons. In Lessons 16 and 17, students examine slices made parallel or perpendicular to a face of a solid before moving to angled slices in Lesson 18. To help students visualize slices, provide them with the right rectangular prism nets included after Lesson 27 (and later, the right rectangular pyramid nets) to build and refer to as they complete the lesson.
