This example demonstrates the calculation of a cube's volume. Key mathematical concepts include geometric volume and measurements in three-dimensional space. Using GeoGebra commands such as Vector, Line, and Intersect, the construction process of the cube is dynamically shown. Suitable for middle school and above students learning solid geometry.
