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:
