Stone Shape, body surface area, and imprisonment [closed]

While examining various uses for stone shape and trying to double check the math on them all (such as cages, jamming doors, making poles, etc) it occurred to me that a use potentially far better than ‘encasing them in a box of rock’ would be instead to do a skin tight encasing of the individual (making it, practically speaking, impossible to move). Granted, for high (18-20) strength characters and creatures I suspect it’d be a full round action to simply break out of it, but I’m curious how the math exactly checks out, and what the exact numbers are. Surface area of a person (or a ‘medium’ creature) would need to be determined, and for small or large creatures there’d be other determinations one would have to make.

Still, it seems to me that it would be using significantly less stone than encasing someone in a box or cage.

It wouldn’t be my go to use, but I can imagine that against say some sort of goblin spell caster, or an evil elf wizard it could have some practical use.
