In terms of buoyancy these two things determine whether an object sinks or floats.
What is buoyant force and weight (force of gravity)?
300
These are the proper metric units for density.

What is copper?
300
This must be true of the buoyant force if an object is sinking.
What is "the buoyant force must be less than weight"?
