How to calculate cubic meters

Often it is necessary to calculate the volume of different substances or objects in a cubic meter ofAh. It is easy to produce in that case, if it is, for example, of bricks or boards. It is sufficient to measure three spatial quantities – the length, width and height. But the situation becomes much more complicated when carrying out calculations of a liquid or relatively liquid substances (cement, water, etc.), for which you cannot use linear measurement tools. In this case, the calculation can be carried out according to the formula.

You will need

• calculator, sheet of paper and a pen in his absence.

Instruction

1. Determine what kind of product do you need to translate. If it is a subject that can be measured by the meter, the definition of cubic metres will not have any problems. Is simply to multiply the value of length, width and height measured in metres of each other. For example, the length – 3 meters, height 1 meter, width – 15 meters. Example calculation – multiply 1 15 and 3. Work values – 45 cubic metres (or cubic meters).
2. Please note that you can only be known mass of the substance, for example, concrete. In this case, you should pay attention to the density of a substance when calculating the number of cubic meters.
3. Perform the following calculations in determining the volume. It is known that each substance has its own specific weight, which corresponds to the weight of one cubic decimeter or one liter (for liquids). So water has a specific gravity of 1.0 kg/dm3. This means that 1000 litres is one cubic meter. Thus, to determine the number of cubic meters, based on existing weight, you need to know the specific weight of the substance.
4. Measure cubic volume be another simple way. To do this, immerse the object whose volume in cubic meters you need to know in the water. The volume of displaced water equals the volume of the object. As the proportion of water, which was above 1.0 kg/dm3, the amount you calculate fast enough.
