Without knowing really what your "results" are, I'll explain to you the importance of surface area to volume ratio.
The volume/surface ratio is frequently used to explain why cells are microscopic. As the cell grows the volume increases faster than the surface area, therefore materials cannot be exchanged adequately to service the cytoplasm. Look up the math for a sphere in regards to how the surface and volume increases as it gets larger.
It is also sometimes used to explain why cells undergo mitosis; they get too large for their own good, so to speak, and split, thus increasing surface area. (You can make it sound more scientific). To a lesser extent, you may also look into the benefits of having long projections, like villi in the small intestine, and microscopic root hairs.
To elaborate on the first part, take for example red blood cells.
Those are very small so they can have more surface area. Let's see the maths behind it: If all RBCs were had a cumulative volume of 8 and a side of 2, this is what the surface area would be.
- 2x2x2 (lbh) = 8 cc
- With a surface area of 2x2x6 = 24 sq cm.
NOW, if we take a volume of 8 again, with side 1 cm...
1x1x1 = 1 cc per RBC. So, 8 RBCs of side 1 will make a volume of 8.
BUT, surface area = 1x1x6 = 6 sq cm per cube surface area. And since there are 8 cubes, that's a total of 48 cm sq surface area.
Clearly, the surface area of smaller sized particles is greater. (Of course, RBCs aren't measurable in whole centimetres. we all know that, but its still true. Smaller the particles, more the surface area, hence more the efficiency). That's more efficient in matters of time, for example.
