How is a net useful when finding the surface and prisms and pyramids?

A net is a two-dimensional representation of a three-dimensional object, such as a prism or pyramid, and it helps visualize how the shape unfolds. By laying out the faces of the object flat, a net allows for easier calculation of surface area by enabling the measurement of each face and summing their areas. This is particularly useful for complex shapes, where visualizing the individual surfaces in three dimensions can be challenging. Overall, nets simplify the process of understanding and calculating the surface area of prisms and pyramids.
