This lesson is a follow up after students struggle through making the biggest box given the same 8.5 x 11 sheet of paper. Students will use their boxes to derive functions, graph, and derive the maximum volume given the same size paper. This activity sheet can be used for grades 6-12. Correlating to CCSS, it serves as a vertical alignment with Geometry, Functions and Graphs, and Calculus. This lesson incorporates the CC SMP.
