Quote:Not at all, we're talking about surfaces at contact, not overall surface above the water , this branch of physics is called fluid mechanics and idhrostatics
We're talking about whether things float.
The mass of water displaced by a body which is floating is equal to the mass of the body. It doesn't matter whether that body is upright, lying down, or perfectly spherical, nor whether it is full of air or full of lead weights.
It should be clear from that that the mass of the part of the body which is above the water is independent of the bodies orientation. What does "surface" have to do with anything, and what is a "surface at contact"?
Also, was idhrostatics a quite spectacular typo of hydrostatics? google has never heard of it . . .
