If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density.
Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density.
If the item sinks to the bottom it has higher density than the fluid.

How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
What are the principle of floating?
An object will float if it has less density than the fluid it is placed in. Floating is the result of the fact that there is a higher pressure at the bottom of the floating object, than at the top.
What is the relationship with a floating object and density?
The density of an object is related to the density of the fluid it is in because if the density of the object is less than the fluid than it will float. If this density of the object is greater than the density of the fluid it will sink to the bottom.
How is density of a floating object related to the density of the fluid it is floating in?
The "AVERAGE" Density of the entire floating object must be LESS than the density of the Fluid. The Average Density includes hollow spaces, etc. That is why a ship made of STEEL can float in water. It has a lot of EMPTY (air filled) space contained in its interior. Therefore, when the Steel Hull is immersed in the water it "DISPLACES" more water weight than the entire ship itself weighs.
What is the effect of buoyancy to the object?
The effect of buoyancy is to reduce the apparent weight of the object when it's introduced into a fluid. Depending on the density of the object compared to the density of the fluid, the object's apparent weight could be reduced to zero (beach ball floating in the pool), or even to a negative value (helium party balloon heading for the sky).

How can density be use to determine whether an object will float or sink in a fluid?
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.
Is it true that ice has less density than water?
True ~ Apex The answer is right there in the question. The density of any floating object is less than that of the fluid in which it floats.
An object will float if?
density of the object < density of the fluid
What would cause and object to float on fluid?
An object would float on a fluid if the density of the object was less than the density of the fluid.

What is the density on fluid of an object sinking?
If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
How do you calculate find the density of an object that floats?
If you can determine the volume fractions of the object that are above and below the water, then you can find the density of the object by multiplying the density of the fluid it floats in by the fraction of the volume that is below the surface of the liquid. Another, more complex way is to weigh the object alone then attach it to one arm of a balance to weigh the object when it is floating. As it floats it will displace an amount of liquid equal in weight to the total object. The decrease in weight will be proportional to the fraction of the object that is submerged. As an example: If an object weighed 100 grams out in the air but only required 20 grams to counterbalance its weight when it is floating, and the fluid it was floating in was water, then the density of the object would be (1 g/cubic centimeter)·(100-20)/100 = 0.8 g/cubic centimeter.
