f two balls have the same volume, but ball A has twice as much mass as ball B, which one will have the greater density? If ball C is 3 times the volume of ball D and ball D has 1/3 the mass of ball C, which has the greater density? If two balls have the same mass, but ball P is twice as large as ball Q, which one will have the greater density? If ball X is twice as big as ball Y and weighs only half as much as ball Y, then which one will have the greater density?
