This Problem Set is a part of the Lesson 7, Unit 5, Grade 5. In this lesson, students apply their knowledge of volume of solids in context. They make connections between models and equations while reasoning about their results to solve problems such as, finding the volume of soil in a planter if the planter is 8 feet long, 2 feet wide, and the soil is 3 feet high. Then they are asked to come up with possible dimensions, given a volume.
