1. F floating = ρ liquid GV row, g row = f floating, g row = mg, then why f floating has nothing to do with quality? 2. Floating F, floating > G, floating = g, but why are they both = g in calculation? 3. When to float with F = ρ liquid GV and when to float with g = f?

Buoyancy is due to the body in the fluid (gas or liquid, the following water instead) due to gravity, there will be pressure, so water for each surface of the object will produce pressure, but the pressure in each direction is different, the force that can be offset (those equal in size, the opposite direction of water pressure) are offset
