I'm given a cube. It's surface area, volume, SA:V ratio, it's diffusion distance (cm) and rate of diffusion using distance (cm/min).
It takes 10 mins to diffuse.
I'm given a cube of 96cm2 or 64cm3 with a diffusion distance of 0.3cm and rate of diffusion distance of 0.03cm/min

How do I work out the rate of diffusion using volume (cm3/min)? The answer is 28.8
