Object A has a mass of 12g and a volume of 8cm3. object B has a mass of 20g and a volume of 8cm3 . which object has a greater density and by how much

Object B has a density of 2.5 g/cm³ which is greater than object A by 1 g/cm³

Explanation:

Since we know that the formula for density is d=m/v, we can divide each mass by its corresponding volume to find the densities

12/8=1.5

20/8=2.5

So we know that object B has a greater density than object A by 1 g/cm³ (gram per cubic centimeter). Also the standard unit for density is kilograms per cubic meter but I used gram per cubic centimeter since they were the given units. 1cm=100m, 1000g=1km
