mass / volume = density
relative density is that compared to water ( 1g / cm3)
you get volume by dividing mass by density or by achimedes/relative density method
mass / volume = density relative density is that compared to water ( 1g / cm3)
One method to determine the density of a solid material is to measure its mass using a balance and then measure its volume using a graduated cylinder or displacement method. Divide the mass by the volume to find the density. For a liquid, one method is to measure its mass using a balance and then measure its volume by using a graduated cylinder or a specific gravity bottle. Divide the mass by the volume to calculate the density.
sand replacement method is used for determining the dry density of soil
I think to the helium pycnometry.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
how density is affected
Density
The Proper way to find the density of an object is by dividing the objects Mass by its Volume. (Density broke my Heart) Mass/Volume = Density
The answer depends on what you were trying to predict.
First 'weigh" the ojbect on a scale. this gives the mass. 2nd use the water displacement method to find the volume. Then divide Density = mass / volume.
Core cutter method is simple but results approximate and used on soft soils
