Day 122: intro to surface area

A lot of students struggle with picturing 3d solids printed in 2d. I decided to start surface area by having students build the figures and compute areas by measuring. Additionally, I want them to understand surface area and what it measures instead of just plugging values into formulas. Hopefully this will give them a point of reference when we move on to more advanced surface area problems. The homework is to complete the examples in their interactive notes.
