What do you call to 2D shapes that make up one surface of a 3D shape?
The flat surfaces of 3D shapes are called faces and are made up of 2D shapes. We can find the 2D shapes on the faces of 3D shapes by looking at the nets of these shapes. A cube has 6 square faces. A cylinder has 2 circular faces and a rectangular face that wraps around the outside.
