Density is mass/volume. Therefore, if you know the mass and the volume, you just do the division:
37.27 g / 6.80 ml = 5.48 g/ml
3 grams per cubic centimeter :D
You calculate density as mass / volume.

The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
Volume of a cylinder = πr²hV= 3.14159 × (3)² × 7V= 197.92 ft³
the density is 5.54g/cm3
density = mass/volume = 36 g / 12 cm3 = 3 grams per cm3
density = mass / volume = 72 g / 36 cm³ = 2 g/cm³
density = mass/volume = 1800g/300 cm³ = 6 g/cm³
3 grams per cubic centimeter :D
2.5 g/cm3
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.

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.
The formula you need is D=m/v, where D is the density, m the mass and v the volume. 1ml = 1cm3 so 12ml = 12cm3 D (in this case) = 4.05/12 = 0.3375 g/cm3
well the volume of the board is 5.54*10.6*199 = 11686.076 cubic cm. and this volume of board weighs 2860 grams. Thus 1 cubic cm of the board would weigh 0.245 grams so the density is 0.245 g/cc
