You determine the volume of the brass standard by using the first formula, and

substituting the given values for the mass and density of brass.

You determine the volume of the stainless steel mass by using the second formula

and substituting the given values for the mass and density of the stainless steel

mass.

Because the buoyant effect is proportional to
