Ask them also why you are wrong.
Do you think that the entire mass is displaced when
it "floats"


Yes. 100% of the time, 100% of the mass of an object must be displaced for it to float. If that requires less than 100% of the volume of the object, then it floats, otherwise it sinks (density at play here).


You are correct for sinking objects though.
