Any material is useful when someone uses it to make something.
Coal is a useful material because it is a major source of energy for generating electricity and heat production. It is also used in the production of steel and cement. Additionally, coal can be converted into liquid fuels and other chemicals for various industrial processes.
Bauxite is a source of aluminum, which is obtained by refining the bauxite ore. Hematite is a source of iron, which is obtained by smelting the hematite ore. Bauxite and hematite are known as ores, as they are naturally occurring materials that can be processed to extract valuable metals.
It is useful to heat materials when attempting to change their physical properties, such as melting or shaping. However, it may not be useful to heat materials that are sensitive to heat and may degrade or become damaged, or when temperature control is crucial for the material's stability.
A property of an ore is that it contains a valuable or useful material that can be mined and extracted profitably.
Finding the volume and comparing it to the mass will give you the density, then it is simply a matter of looking up which materials have that density to find what it is. And that is how you can tell how the density can be used
The material is simply:felt. I hope this was useful to you!

It is the material that is used to make clothes.

Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
We process materials to make them better and more useful. We are therefore we are modifying the natural material to advance it.
Valuable minerals, useful material, and eventually consumer products.
