Geometry: Surface Area and Nets

The video tutorial explains the concept of nets in mathematics, which are two-dimensional representations of three-dimensional objects. It covers how to draw nets for cubes, prisms, and pyramids, and demonstrates how these nets can be used to calculate the surface area of these shapes. The tutorial includes examples and encourages viewers to practice identifying and drawing nets.
