Rectangular Prism: 3D Construction and Visualization

① This example demonstrates how to construct and visualize a rectangular prism (cuboid) in GeoGebra's 3D view, showing its vertices, edges, faces, and internal structure. ② Core mathematical concepts include solid geometry definitions of prisms, properties of a cuboid (six rectangular faces, twelve edges, eight vertices), points and vectors in 3D coordinates, and the relationship between polygons and prisms. ③ Construction highlights: from the summary, the Polygon command creates the base rectangle poly1, then the Prism command extrudes it with a given height; multiple points (A, B, C, D, E, F, G, H, I, J, K, L) and edges (edgeBI, edgeCJ, etc.) are defined, and faces are named (faceBCJI, faceIJKL); Circle and Point commands are also used, possibly for auxiliary annotations or reference elements. ④ Suitable for middle/high school solid geometry lessons, helping students intuitively understand cuboid structure and spatial reasoning, and as an introductory 3D modeling example.
