Common Solids:
1. Cube: Six square faces.
2. Sphere: Perfectly round, no flat surfaces.
3. Cone: Circular base, tapers to a point.
4. Cylinder: Two circular bases, connected by a curved surface.
5. Pyramid: Base is a polygon, sides are triangles meeting at a point.
6. Prism: Two congruent bases, connected by parallelograms.
7. Tetrahedron: Four triangular faces.
8. Octahedron: Eight triangular faces.
9. Dodecahedron: Twelve pentagonal faces.
10. Icosahedron: Twenty triangular faces.
Less Common Solids:
11. Truncated cone: A cone with the top cut off at an angle.
12. Frustum: A pyramid or cone with the top cut off.
13. Torus: A donut shape.
14. Ellipsoid: A 3D version of an ellipse, like a squashed sphere.
15. Paraboloid: Shaped like a satellite dish.
16. Hyperboloid: Two sheets connected by a narrow waist.
17. Hyperbolic paraboloid: A saddle-shaped surface.
18. Möbius strip: A single-sided surface.
19. Klein bottle: A bottle that passes through itself.
20. Platonic solid: A regular polyhedron with all faces, edges, and angles identical (cube, tetrahedron, octahedron, dodecahedron, icosahedron).
