Mathematically, surface area is a squared dimension while volume is cubed. 3 squared is 9, but cubed it's 27. 4 squared is 16, but cubed is 64. Volume gets much bigger much faster because it's working in three dimensions.

The whole is thing is a catch 22. The cell wants lot of surface area in order to move stuff in and out quickly, but wants a small volume to move stuff across itself really quickly. You can't have both.

But a smaller cell has a better surface area to volume ratio, which means the difference between the total surface area and the total volume isn't that large. Good ratio = efficient cell.
