| Cuboid | 6 | 12 | 8 | No | Yes |
| Cylinder | 2 flat + 1 curved | 2 | 0 | Yes | Yes |
| Cone | 1 flat + 1 curved | 1 | 1 | Yes | Yes |
| Sphere | 1 curved | 0 | 0 | Yes | No |
Common Errors:
- Confusing faces with edges
- Thinking sphere has 1 face (it's curved, not flat)
- Confusing cylinder and cone properties
