How does the mass relate to volume and density?

Answer 1

Mass relates linearly to volume and density. That is to say if you have twice as much volume of the same material (say water) it has twice the mass. If you have something twice as dense at the same volume, it has twice the mass.

Note: this applies specifically to mass-density, the most common use of the word. Things like energy-density or population density have a more complicated and often less meaningful relation to mass.

Answer 2

i am in third grade but i think i know it.

mass relates to voluam by mass pushes up on voum

and volume pushes down on mass
