Density (or more properly Relative Density) is an elemental property. An object made from one or more elements will have a density related to the density of the elements.

How can diffreent objects have the same density?
Different objects have the same density if they're made of the same substance.Density is a property of the substance, not the object.
Calculate the weight of a solid object?
If the object is made of only a pure element or a pure compound whose density you could look up, you could multiply the density of the substance by the volume of the object, then, assuming you are on or near Earth's surface, multiply the product by 9.8 m/s^2.
What determines how well an object floats?
if it is lighter than the amount of liquid it displacesIf the density of the object is lower than the density of the liquid, then it will float. If the object is denser than the liquid, then it will sinkThe answer is just density lolAn object will float if its density is less than its environment. Or, another way, an object will float if it weighs less than the volume of the gas (or fluid) that it displaces.
What can you infer about density of a substance floats in water?
You can infer very little about the density of the substance. Ships made of steel, with a density much greater than that of water, can float.
Density of object made of 2 different meterials?
Still the object's mass divided by the object's volume.The density of the composite object will be somewhere between the densitiesof the two different materials.

Is the density of an object bigger in one piece or two?
The answer to that question is: No. The density of an object only depends on the substance its made of. If two samples are made of the same substance, then it doesn't matter if one is the size of a grain of sand and the other is the size of a battleship ... they have the same density.
How will knowing the density of a substance help you determine wether an object made from that material will float in water?
If it is lower it will float
Which has the greatest density a small piece of aluminum or a large piece of aluminum?
density has nothing to do with the size of an object in the way that you are thinking, density is the mass or weight of an object per unit of measurement Neither
What is the property that can be observed without changing what a substance is made of?
there is no property that can be observed without somehow changing the identity of the object due to Heisenberg's Uncertainty Principle.
How will knowing the density of a substance help you determine whether an object made from that material will slow in water?
I am assuming that you mean float (or sink) rather than "slow". Knowledge of density will not help - unless the object is compact. The density of iron is greater than that of water but ships made of iron will float.

What the weigh for 2mm x 48in x 84in in kg?
The answer will depend on the density of the substance that the object is made from. Since you have not bothered to provide that information, I cannot provide a sensible answer.

Does density vary with the of volume of a body?
The density of an object is its mass divided by its volume.The density of an object varies inversely with its volume.Thus, if you can compress and object, like a sponge, you can increase its density.Normally, we say the density of a type of material is an intrinsic property, i.e. if you have a big piece of it or a small piece of it, they both have the same density because the large piece has a proportionately larger volume than the small piece.So, a gallon of water has the same density as a milliliter of water.Note the distinctions here.1. An object, like a car, can be made of many different materials and the object, as a whole, has some density which is the mass of the car divided by the volume of the car. If you crush the car, you increase its density.2. Each type of material also has a density. The glass in the window of the car has its own density, a property inherent in that type of glass. The steel in the car has the density of steel, a property inherent in that type of steel.If you have a type of material and you compress it, you increase its density.If you don't compress it, then two different pieces of the same uniform material, large or small, will have the same density under the same conditions of pressure and temperature. That is what we mean by density is an intrinsic property of a material.
How will the density of a substance help you determine whether an object made from that material will float in water?
The density of water is roughly 1 gram/cm3. If the density of the substance is less than that, then a solid lump of it can float. Otherwise it can't, but you can form the lump into shapes that can float, just as plate steel is formed into the shape of cruise ship or an aircraft carrier.
