How is density calculated?

Mass divided by volume
Volume divided by mass
Mass multiplied by volume
Volume multiplied by density

The correct answer is: Mass divided by volume

This question is asking about the formula for calculating density, which is a physical property of a material. Density is a measure of how much mass is contained in a certain volume of the material. The correct formula for calculating density is mass divided by volume, which is option A. Options B and D are incorrect because they involve dividing or multiplying by density, which is not part of the formula for density. Option C is incorrect because it involves multiplying mass and volume, which is not the correct method for calculating density. So, the formula for calculating density is mass divided by volume, which means that the amount of mass is divided by the space it takes up.
