When its density is less than the fluid in which it is placed
An object will float if it is less dense than the fluid it is sitting in. If the object is denser than the fluid, it will sink.
The specific object or material of interest needs to be specified to determine if it would float with ease. Factors like density, shape, and volume play a significant role in determining whether an object will float or sink in a given liquid.
If the density of an object is 1, it will neither sink nor float in water. When the density of an object is equal to the density of the fluid it is placed in, it will be neutrally buoyant and will remain suspended in the fluid at the same level.
I will assume that you are asking if it will float in water. That depends on the shape of the object and it's density, or you could say it depends on the effective density of the object where that takes into account any voids inside the object. If the material the object is made of is less dense than water, then the object will float. If the material the object is made of is denser than water and there are no internal voids, then it won't float. If the material the object is made of is denser than water but the object has sufficient internal voids so that its effective density is less than that of water, then it will float.
If you try to find the density of an object with a density less than water, the object will float in water. This indicates that the object is less dense than water. To find the density of such an object, you would divide the mass of the object by its volume.
An object would float on a fluid if the density of the object was less than the density of the fluid.
[object Object]
That depends on the object's density, not just on its volume. For example, the object you mention would float if it has a mass of less than about 3.7 gramms.
when a object float it has density
There is no answer to this question as the 3.8 has no units and there is no mention of what the object would be in.
An object will float if it is less dense than the fluid it is sitting in. If the object is denser than the fluid, it will sink.

the application is that an object can float of
The object would float in a given liquid.
If the density of an object is 1, it will neither sink nor float in water. When the density of an object is equal to the density of the fluid it is placed in, it will be neutrally buoyant and will remain suspended in the fluid at the same level.
It would float.
