📚 Topic Summary
3D shapes are not flat like squares or circles. They have length, width, and height! Think of a cube or a pyramid. An edge is where two faces of a 3D shape meet. It's like the line you see when you look at a corner of a box. In this worksheet, we will explore the edges of different 3D shapes!
