I have a multiple choice question where a rock weighs 1400 N in air and 900 N apparent weight in fresh water with 998 kg/m^3 density (i think), The question is what is the volume of the rock. 2 of the choices are .14 m^3 and .051 m^3. I have tried(adsbygoogle = window.adsbygoogle || []).push({});

p = m / v and 1400 - 500 and division by g's and densities, i have come too both of these conclusions many different ways, coming to either answer about the same amount of times. Does anyone know the true formula for this problem.
