This example demonstrates the volume calculation of a square-based pyramid. Key mathematical concepts include the volume formula for a pyramid and geometric construction. Using GeoGebra commands such as Cube, Net, Polygon, and Pyramid, the various faces and edges of the pyramid can be constructed. Suitable for high school mathematics education and learning.
