What problems should be paid attention to when calculating buoyancy with Archimedes' principle: f-floating = g-row = ρ liquid gv-row

Archimedes principle: F floating = g row = ρ liquid GV row. When calculating buoyancy, we should pay attention to: 1. G is the weight of the liquid, 2. ρ liquid GV, ρ is the density of the liquid, g = 9.8,3, V is the volume of the liquid
