This example demonstrates how to calculate the volume of different 3D shapes using geometric construction. Key mathematical concepts include solid geometry and coordinate geometry. Using GeoGebra commands such as Line, Intersect, Rotate, etc., 3D shapes are constructed and their volumes are calculated. Suitable for high school mathematics education and learning.
