✨ What are Nets of 3D Shapes? A net is a 2D pattern that folds into a 3D solid. This interactive flipbook contains 28 different nets — from basic cubes and prisms to advanced polyhedra like Dodecahedron and Icosahedron. Click any card to flip it over and discover the shape name, number of faces, edges, and vertices! Perfect for grades 4-10 and geometry enthusiasts. 🧠📐
