Surface Area to Volume

Would the rate of diffusion be effected, if the shape of two objects are different but the surface area is the same?

Also does the volume need to be the same?

no, the rate of diffusion (in like cm/min) will be the same, but you are probably interested in how long will it take untill the whole volume will be filled, rigth?

Yeah, sorry i didn't phrase the question very well...

in such a case, you're looking for number, which describes, how far is the farest point from the surface.
I.e. imagine a globe, whose farest point is the exact middle being r cm far from the surface, on the other hand, if you got something flat like pancake or flatworm ( http://www.biolib.cz/en/taxon/id14937/ ), every point will be pretty close to the surface, rigth?
