density = mass / volume
= 72 g / 36 cm³
= 2 g/cm³
You need to divide the mass by the volume.
It is 2 grams per cm3.
Since density = mass/volume, D = 25/10 = 2.5g/cm^3
density = mass/volume = 36 g / 12 cm3 = 3 grams per cm3
An object has a mass, say M It also has a volume, say V A useful relation between the above two is the ratio M/V which is defined as the density of the object. It is the mass of an object whose volume is unity. In solids and liquids, the density remains constant over temperature ranges and pressure ranges. But in gases the density is affected by temperature and pressure.
100 g / 10cm^3 = 10g/cm^3
It could be a solid object made with a mixture of materials whose average density is 5 grams per cm3 or it could be a hollow object made with materials whose density is higher.
Density = 2.991 g/cm3
Since density = mass/volume, D = 25/10 = 2.5g/cm^3
density = mass/volume = 36 g / 12 cm3 = 3 grams per cm3
3 grams per cubic centimeter :D
There can be no possible answer to this question. Volume cannot be measured in g. Mass cannot be measured in cm - nor can volume.
2.5 g/cm3

The question, as presented, is total nonsense since volume cannot be measured i cm. A centimetre is a measure of distance, not volume. The appropriate measure for volume is cubic centimetres or cc. Density = Mass/Volume = 36 g/12 cc = 3 grams per cc.
You calculate density as mass / volume.
It will float in water, and in any other fluid whose density is greater than the object's density.
