Other surface areas
| Shape | Formula | Description |
| Cube | 6 x Length x Width | A cube is made up of of six square surfaces with same area. |
| Cuboid | (2 x Height x Width) + (2 x Height x Base) + (2 x Base x Width) | Each pair of triangles have same area, total three pairs. |
| Cylinder (solid) | 2Πr 2 + 2Πr x height of the cyclinder | |
| Cone (solid) | Πr 2 + Πrl | l refers to slant height |
| Sphere | 4Πr 2 |
r = radius
