Well draw a cube of length 1 units, it has a volume of 1 unit cubed. A cube with length 3 untis long, will have a surface area of 27 units cubed. You can see the SA:VOL is this:

6:1
54:27

We can see immediately that there is a reduction in SA:VOL ration, which means if it was a single celled organism the O2, from the first SA:VOL is better as more SA for O2 uptake, for the volume of cell.
