Many reference sources are available that give the density of different compounds. For example this tool can be used to calculate the amount of storage volume required for a given quantity of substance mass. The density calculator uses the density formula.
Place your object on the scale to find its mass.
1 gcm 3 1 11000 kg 11000000 m 3 1000 kgm 3. So when you input the parameters you get approximately 30159 cm cubed. If you are calculating densities of liquids or gasses especially you will need to know the. 1 gcm 3 1 11000 kg 11000000 m 3 1000 kgm 3.
