When floating, buoyancy is equal to gravity, g = mg, and M refers to the mass of the drained water or the self generated weight of the object

When floating, buoyancy is equal to gravity, g = mg, and M refers to the mass of the drained water or the self generated weight of the object

Floating: F floating = g object, which is based on the balance of two forces. At this time, G object = m object G, where m refers to the weight of the object itself
Floating: F floating = g row, which is based on Archimedes principle. At this time, g row = m row g, where m refers to the mass of the object's boiled water
In fact, at this time, m object and m row are just equal, that is to say, the mass of the discharged water is equal to the mass of the object
