We began working on calculating Total Surface Area of a 3-D figure today! Students first learned that they have to break the figure into a “net” or a blueprint of the shape once it’s cut and laid open on a flat surface. In our discussion, we determined that if we **find the area of each shape** in the net and **then add up all those areas**, we could give a **total surface area of the figure. **Here are some examples we did together in class:

Net of cube showing total surface area

Net of square pyramid showing total surface area
