The table below shows how the surface area to volume ratio of spherical nanoparticles changes as their diameter increases.
| Diameter of nanoparticle (nm\text{nm}nm) | Surface area : volume ratio |
|---|---|
| 16 | 3:83:83:8 |
| 32 | 3:163:163:16 |
| 48 | 3:243:243:24 |
| 64 | 3:323:323:32 |
| 80 | 3:403:403:40 |
