This example demonstrates the calculation method and geometric significance of the surface area of a rectangular prism. It involves core mathematical concepts such as area calculation of geometric figures, vector operations, and polygon construction. GeoGebra commands like Vector, Translate, Polygon, Line, Intersect, and Midpoint are used to dynamically construct and measure the图形. Suitable for middle school students and above learning solid geometry, vectors, and geometric constructions, or for classroom demonstrations.
