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.
