Volume, a word that can describe the thickness or size that has a certain object. Similarly, the term used to identify the physical quantity information on the extension of a body in relation to three dimensions (height, length and width). Within the international system, the unit that corresponds is the cubic meter (m3).
It is also interesting to note that as a physical quantity, recognizes three types of volume units: the solid volume (used to measure the volume of a body through length units that rise to the third power), liquid volume units (developed to establish the volume occupied by a liquid contained in a container) and the aggregate volume units or units of capacity (which allow calculation of the volume occupied by the crop which are stored in silos and barns).
Regarding the different units of measurement to the International System of Units set we stress that in the case of solid volume we find the cubic meter, cubic kilometer, cubic hectometer or the cubic decameter. However, the English system measures instituted as cubic inch, cubic foot or cubic mile, among others.
On the other hand, the system determines that the measures to be used to calculate what is the liquid volume are the liter, kiloliter, centilitre, decaliter or milliliter, for example. The English, as in the previous case, and the Americans have their own measures and in this case these are the barrel, the fourth, the look, the fluid ounce, tablespoon or cup.
As regards the sound, the volume rate is a subjective perception in relation to man power. The intensity of sound is determined from the amount of energy (called acoustic power) that passes through the second surface. A more powerful, stronger volume. One thing that should be kept in mind is that volume and loudness are not synonymous, since the latter is named how subjectively perceived intensity.
