Density.
An object will float in a substance if its density is less than the density of the substance.
The density of water is 1 kg /L or 1 g/ cm3. Anything with a density less than this will float.
Density
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
by dividing mass by volume you get density which is how you determine as the density increases the chance of floating decreases It will remain suspended if the mass and the volume is equal It will sink if the mass weighs more than the volume and it will float if the mass weighs less than the volume
The "average" density of the object must be less than that of the water displaced.
It will sink in the fluid. It will sink in the fluid.

density
The object's density relative to the fluid. If the object is denser than the fluid it will float; if it is less dense it will sink.
density
The object's density.If less than the density of the fluid, the object floats.If more than the density of the fluid, the object sinks.
The density of an object determines whether it will float or sink in water. If the object is denser than water, it will sink. If it is less dense, it will float.
An object will float in a fluid if it is less dense than that fluid, because the mass of that object displaces less of the fluid than is the volume of the object. An object denser than that fluid would continue to displace the fluid until it met something either solid or more dense.

Density
When you have the density of both the object and the fluid, just see which has a higher density. If the object has a higher density than the fluid, the object will sink. If the object has a lower density than the fluid, the object will float.
