What is the-formula for for density?

Answer 1

The formula for density is D=m/v (Density equals mass over volume)

This means that density is equal to the amount of matter "stuff" in an object in a certain amount of space, or volume. In SI units, density can be measured in kilograms per cubic meter , or grams per cubic centimeter.

Recall that we see density written like these examples:

13.534 grams per cubic centimeter (density of metallic liquid Mercury)

1 pound per cubic foot (density of a "common" form of styrofoam)

Note that the volume measurements are in units, or in "just one" of the specified volume measures. We reduce the volume to get a "one" or to get that single unit. For instance, if we had styrofoam, and we measured 2 pounds of it and it had the volume of 2 cubic feet, we'd reduce that by dividing by 2 so we could get a single unit of the specified volume in our statement of density.

A last example might be that if we had 45 grams per 3 cubic centimeters, we'd have 15 grams per cubic centimeters after the division to get that single unit volume.

Answer 2

Density = mass / volume

Density is a measure of how heavy something is in proportion to how much room it takes up.

For example, a kilogram of bricks and a kilogram of feathers weigh the same but the feathers would take up a lot more space. We say 'feathers are less dense than bricks'.

Answer 3

Density is equal to to (mass)/(volume) .
