PolygonSolid GeometryGeometric Construction
In collections Grade 6 Unit 1: Area and Surface Area
This GeoGebra example demonstrates the surface area of a prism by dynamically displaying its base polygons, lateral faces, and edges, helping students visualize how total surface area is composed of base areas and lateral rectangular faces. Core mathematical concepts include solid geometry, surface area of prisms, polygon area composition, and additive area measurement. The construction uses GeoGebra commands Polygon and Prism to build base polygons (poly1_2, poly1_3) and the prism solid, with labeled vertices (A_2–H_2, A_3–G_3), edges (edgeAE_2, edgeBF_2, edgeCG_2, edgeDH_2, edgeEF_2, edgeFG_2, edgeGH_2, edgeEH_2), and faces (faceABFE_2, faceBCGF_2, faceCDHG_2, faceADHE_2, faceEFGH_2). It is suitable for middle school (Grade 6–7) geometry instruction, classroom demonstrations, surface-area concept introduction, and independent student exploration.
