Nets of 3D Shapes

The video introduces the concept of nets for 3D shapes, explaining how a net is a flat representation of a 3D shape. It provides examples and exercises to help viewers visualize and identify nets for various shapes, including cubes and triangular prisms. The video encourages active participation by asking viewers to draw and fold nets, and concludes with a challenge to identify incorrect nets.
