Understanding Nets in Solid Geometry

The video tutorial introduces the concept of nets in solid geometry, focusing on how two-dimensional figures can be folded into three-dimensional solids. It uses the example of a cube to explain the process and encourages viewers to visualize and practice folding nets. The tutorial also suggests practical exercises, such as drawing and cutting out nets, to enhance understanding. Finally, it encourages creative exploration of different nets for various solids.

What is a net in the context of solid geometry?
