Question: 1 / 400

What is the formula for density?

Density = Mass + Volume

Density = Mass x Volume

Density = Mass / Volume

The formula for density is defined as the mass of an object divided by its volume. This relationship is expressed mathematically as Density = Mass / Volume.

Understanding density is important in various fields such as physics and engineering since it provides insights into how much matter is contained in a particular space. For example, if you know the mass of a substance and the volume it occupies, you can easily calculate its density, which can help you compare different materials or determine how they will behave under different conditions.

The other choices do not correctly represent the relationship between mass and volume when calculating density. Adding mass and volume, or multiplying them, does not yield a meaningful concept of density. Additionally, the idea of volume divided by mass does not accurately describe the concept of density either, as density fundamentally expresses how much mass exists in a given volume.
