> tank mass scales with a lower exponent than tank volume

I'm confused here. How are they not both cubic?

It's the mass of the empty tank that's relevant here, because non-propellant mass is what you want to minimize in order to increase deltaV.

Tank dry mass scales (approximately) with surface area.
