Well to get density you have to devide mass by volume: Density= Mass Volume Since you are given the mass and the density and you are looking for volume, simply fill in the bits of information you have into the equation above. 70= 50 Volume (take volume as X) Then cross multiply to get the volume: 70X=50 X=50/70 X= 0.714
