Lesson 10
Represent Volume with Expressions
Lesson Purpose
Lesson Narrative
In previous lessons, students used formulas to find the volume of right rectangular prisms.
They also learned to apply these formulas to find the volumes of figures made up of two
non-overlapping right rectangular prisms. In this lesson, students use what they have
learned to write and interpret numerical expressions in the context of finding the volume of
figures composed of rectangular prisms (MP2).
Students recognize that subtraction can be used to find the volume of figures composed of
two non-overlapping rectangular prisms.
