Year 11 Human biology help!!?

[cryocell]

Hi, i have some human biol homework,
im not asking you to do it for me..
i just need to know,
how to work out..
the SA:VOL ratios...
like surface area to volume ratios

i have the surface area and the volume of each "cube/cell"
but i need to know how to put it together
and then graph it...i dont understand how im supposed to graph, or work it out

any help would be great!!

SA = 6 face * area of each face = 6* (sidelength^2)
Volume = sidelength^3

SA:Vol ratio is just SA/Vol

So pretend the ratio is y, and sidelengths are x and plot.
