PolygonSolid GeometryGeometric Construction
This example demonstrates the structure of a cuboid and its net. It involves core math concepts like solid geometry, polygons, volume calculation, and spatial visualization. The construction uses GeoGebra commands such as Polygon, Prism, and Net to build the cuboid and its展开图. Suitable for middle school students and above learning about solid geometry and the transformation between 3D shapes and 2D plane figures.
