Several:
colour,
shape (so long's it's mostly convex),
age (so long's it's not further changing its properties with age),
country of manufacture,
surface texture (so long's it doesn't trap significant amounts of air),
etc...
You need to ask the question a different way.
Density
An object's density influences its buoyancy, thus determining whether or not an object will float
No, every object has a fixed density. if the density is less than water it will float. If not, it wont. Hope this answers your question!
Density.
Density
no and mass is air
Density
An object's density influences its buoyancy, thus determining whether or not an object will float
Whether an object floats or not does not depend on whether it is magnetic. An object will float if it is less dense than the fluid in which it is placed.

the object's density
Yes. If the object is in a lower gravitational pull, like the object is in the moon then it can float. But if it the object is in the Earth ,then the object will not float, also in water. But boats and ships are different cos it has a property or structure that make them float.
density!
if its in water and it has less grams per cm cubed than the water does then it will float and vicevesa
density
Density.
No, because you can predict if an object will sink or float mostly on density.
