I am not very strong in phsyics, but if I remember correctly the conservation laws imply that the mass of the man is equal to the mass of the water that is displaced.

Volume of the water displacement is $$\pi r^2 h = \pi (100 \sqrt{2})^2 (1)=62832$$. This would be the mass of the water also, since, 1 cc of water has a mass of 1 g (I think that is right anyway).

So it looks like the guy is 62.8 kilos if you convert into more standard weighing units.
