This Instructional Activity is a part of the Lesson 16, Unit 5, Grade 6. How can we use the dimensions of a rectangular solid to figure out the dimensions of the polygons that make up its net? The length, width, and height measurements of the solid will be paired to become the length and width of the rectangles. How many faces does the rectangular prism have? What are the dimensions of the top of this prism? What are the dimensions of the bottom?
