How to translate the volume-to-mass

Any object has mass and volume. And this is - an axiom. But, besides these two parameters, there is a third is density of the substance, which consists of a body (fluid). Knowing the density of the body quite easily translate volume to weight.

You will need

• Know from the table the density of a substance the exact density, which characterizes the substance of the original body.

Instruction

1. For clarity, it is necessary to consider an example. For example, given a concrete block, the volume of which is 4 m?. Now, turning to the table of densities of various substances shows that the density of concrete is 2300 kg/m?
2. Now, according to the formula for finding body mass, you can calculate:
   m = 2300*4 = 9200 kg.
   Thus, the mass of the concrete block with a volume of 4 m? will amount to 9.2 tons.
