Regular Pyramid Surface Area and Volume

① This GeoGebra example dynamically illustrates the surface area and volume of a regular pyramid, allowing users to adjust the number of base sides, side length, and height to see real-time changes in the 3D solid and its net. ② Core mathematical concepts include the formulas for surface area (base area plus lateral area) and volume (V = 1/3 × base area × height), properties of regular polygons, and spatial relationships among vertices, edges, and faces. ③ Construction uses GeoGebra commands such as Point, Segment, Polygon, Pyramid, Net, Volume, Midpoint, and Perimeter, with objects including n (number of sides), s (side length), h (height), vertices A, B, and side faces (faceABD, faceBCD, etc.). ④ Suitable for middle and high school geometry, this interactive tool helps students visualize and understand measurement formulas, and explore how changing the base shape affects surface area and volume.
