Density = mass/volume.
Density(A) = 40.2/5.7 = 7.05 gcm-3
Density(B) = 42.0/6.3 = 6.67 gcm-3
So B is less dense.

How many kiloliters are in 3000 grams?
Kiloliters is a unit of volume or capacity; grams is a unit of mass or weight. They are not comparable. How many grams of a substance fit in a kiloliter depends on the density of the substance. For example, 1 liter of water weighs 1 kilogram or 1,000 grams. So 3,000 grams of water takes up 3 liters, or 3/1000 (0.003) of a kiloliter.
