Block A of an unknown metal has a volume of 125cm^3 . Block B of a different metal has a volume of 145cm^3. If block A has a greater mass than block B, what can be said if the relative densities of two metal?

mass = volume*density
So, if A has more mass than B, then if their densities are a and b,
125a > 145b
a/b = 145/125 > 1
so, a > b, so A is more dense than B.
