What are volume and density ? how do they relate to each other?

The SI unit for density is kilograms per cubic meter. However, often grams per cubic centimeter or grams per milliliter, which are equal (1 cubic centimeter = i milliliter), is used. In order to find the density of a substance, you divide its mass by its volume.

Volume is the amount of space that a substance or object occupies. Density is a measure of mass per unit of volume. In order to find the density of a substance, you divide its mass by its volume, and that is how they are related.

since there are no options posted i'll give you a few examples.
