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.
m = 2300*4 = 9200 kg.
Thus, the mass of the concrete block with a volume of 4 m? will amount to 9.2 tons.
Note
Before doing the translation of volume to weight, you should always remember that the units must be converted to SI units: kilograms and meters. Therefore, if the original data specified units, other than those given above (e.g., grams, milligrams, centimeters, millimeters), it is necessary to translate them. For their translation we need to know:
1 kg = 1000 gr. = 1000000 mg.
1 m = 100 cm = 1000 mm.
1 kg = 1000 gr. = 1000000 mg.
1 m = 100 cm = 1000 mm.
