The relationship between the object's volume and its weight, commonly combined
in a single number called the object's 'density'. That's the whole story right there,
in a nutshell, and it doesn't even have anything to do with the object's size. If the
object's density is less than the density of the substance you drop it into, it floats.
If greater, it sinks. You can't get any more direct than that.
the object's density
The density of the object compared to the density of the fluid it's placed in is the primary factor influencing whether or not an object will float. If the object is less dense than the fluid, it will float; if it is denser, it will sink. Objects that are less dense than water, for example, will float in water.
An object will float if it has less density than the fluid it is placed in.For example, in the specific case of water, some objects that will float on it is anything made from most woods and most plastics.
Take the mass and divide it by the volume. The most common units for density is g/m or lb/cu ft WHEN? There are many applications, but the most common application is to determine whether or not the object would sink/float. Since water's density is roughly equal to 1, objects with a density less than 1 should float.
The density of an object determines if it sinks or floats. If an object is more dense than the medium it is in, it will sink. If it is less dense, it will float. Therefore, the most dense things typically sink.
An object floats in liquid when the weight of the liquid displaced is equal to or greater than the weight of the object. This creates an upward buoyant force that supports the object's weight, allowing it to float. Objects that are less dense than the liquid they are in will float, while objects more dense will sink.
Many things can float in water. An object will float based on 2 main factors. They are density and shape. If an object is too dense, it will sink. But why would shape matter? The shape of the object affects how the water is displaced. If the weight of the water displaced is more than the weight of the object that is touching the water, the object will float. So the shape affects how much water is displaced therefore determines if an object will float.

The density of most of the woods are less than 1. That's why they are floating in water. The buoyancy force of water will help the woods to float on water if it's density is less than the density of water.
