APPENDIX 1 An arithmetical investigation of the relationship between surface area and volume
Its effectively an exercise in looking at one of the most important properties of nanoparticle materials, namely, their very high surface area to volume ratio.
Another approach to this kind of arithmetical exercise is to derive a simple equation from the geometrical equations for a sphere.
This is a better approach than above as nanoparticles are more likely to be nearer a spherical shape than a simple cube, though many textbooks use the cube to illustrate the idea (because its simpler maths I suppose). So, using r as the radius of the spherical particle, the final equation is very simple!
So, you can clearly see that as r gets smaller, the surface area to volume ratio increases.
Same result as in 1b: The smaller the particles the greater their surface area to volume ratio.
