The three types of matter occupy some space, hence they have a definite volume. The different matters have a density also. The density is the packing of the materials like solid objects are more tightly packed than the liquid and gases. The quantity of all the materials is measured by the mass. It means how heavy the object is known as the mass. By measuring the mass of an object one can measure the quantity of a matter.
