This example demonstrates the net of a cuboid. Key mathematical concepts include solid geometry and geometric construction. Using GeoGebra commands such as Intersect, Vector, Rotate, etc., the net of a cuboid can be constructed. Suitable for middle school and above students to learn solid geometry.
