Introduction to surface area of 3dimensional shapes
Imagine you are looking at a 3dimensional shape, for example, a cereal box. It looks like large rectangle from the front. From the side, it may look like a much thinner rectangle. However, you are sure that it is the same cereal box. It is because 3dimensional shapes have many surfaces, and they do not necessarily look the same from different angles.
