1. The problem statement, all variables and given/known data How does one experimentally measure an irregular object's volume given that said object floats on water? 3. The attempt at a solution It seems to me that the simplest solution to this is to submerge the whole object by pressing down on it to the point that only the object is submerged. I'm thinking that the volume of displaced water would equate to the volume of said object, regardless of densities or forces being applied. Am I correct?
