Oh I hate these..... it's a bit like the weight of the pigeon flying in the aircraft isn't it? You know this already Chewy you rascal and so it's a trick question isn't it? It depends on the pressure we take her (or boeing takes her to) of course as it's all about pressure differential Inside to outside of the tibe isn't it? Effectively the aircarft becomes the atmosphere.
FWIW at max operating altitude of 41000ft we hold the cabin altitude at 8000ft and the pressure differential is close to 9psi.......
Some guys insist on deflating the kids footballs as the 5psi increase in pressure might burst them.
