How is density calculated for an object?

Density is a physical property of matter that describes how much mass is contained in a given volume. It is defined mathematically as the mass of an object divided by its volume. This relationship can be expressed through the formula:

Density = Mass / Volume

By using this formula, you can determine how dense an object is, which helps in comparing different materials and understanding buoyancy and stability in various contexts. This is particularly important in fields such as engineering and physics, where the density of materials affects performance and functionality.

The other options involve incorrect mathematical operations (addition, multiplication, and subtraction) that do not accurately describe the relationship between mass and volume for calculating density.
