Mouhe Fanggai: Intersection of Two Cylinders

This GeoGebra applet dynamically demonstrates the 3D construction of the 'Mouhe Fanggai' (Steinmetz solid), which is the intersection of two cylinders of equal radius with perpendicular axes. It visualizes the solid's surface, cross-sections, and geometric properties, providing an intuitive understanding of solid geometry and the classical calculus problem of calculating its volume.
