This example demonstrates the folding process of a box. It involves concepts of solid geometry such as area, surface area, and volume. Using GeoGebra commands like Sequence, Element, and Polygon, the dynamic folding of the box's faces can be shown. Suitable for middle school and above students to learn solid geometry and geometric construction.
