Volume determines the space size which is occupied by any body. This size is connected by constant ratios with other characteristics of physical bodies - their geometrical sizes, weight and density. Therefore measurement of these additional parameters can become base for calculation of volume, for example, of a vessel.
Instruction
1. If there is an opportunity to fill a vessel with water, then for determination of its volume it is enough to have any measured form. Depending on the vessel sizes the syringe, a graduated cylinder, a glass, bank, a bucket or any other ware which capacity is known to you can become measured ware. Having picked up a suitable measuring vessel, fill with water to the brim the vessel investigated and then pour water in a measuring vessel, counting thus volume.
2. If to fill the studied vessel with liquid there is no opportunity, but it is possible to place it in liquid, then determine volume by amount of the water which is forced out by it. For this purpose too any measured ware will be required. Having filled it partially with water, note level, then place the studied vessel in measured ware so that it completely appeared under water, and make the second mark. Then determine a difference of volumes of measured ware by a difference of two made marks.
3. If there is no measured ware, but there is an opportunity to weigh a vessel, then define a difference between a vessel empty and filled with water. That one cubic meter of volume has to contain water weighing one ton, calculate vessel volume.
4. If the vessel has geometrically regular shape, then its volume can be calculated, having measured the sizes. For finding of volume of a vessel of a cylindrical form (for example, pans) should be measured diameter (d) of its basis (pan bottom) and its height (h). Volume (V) will be equal to one quarter of the work of the squared diameter on height and Pi's number: V=d² ∗ h ∗π/4.
5. For finding of volume of the vessel having the sphere form it is enough to determine its diameter (d). Volume (V) will be equal to the one sixth part from the work of the cubed diameter on Pi's number: V=d³ ∗π/6. If it is simpler to measure length of a circle (L) spherical vessel in its widest part (for example, by means of centimeter), than to measure diameter, then volume can be calculated also through this size. The cubed length of a circle should be divided into Pi's number increased six times squared: V=L³ / (π² ∗ 6).
6. For finding of volume (V) squared vessel, it is necessary to measure its length, width and height (a, b and h) and to multiply the received values: V=a∗b∗h. If this vessel has the cubic form, then build length of one his edge the third degree enough: V=a³.
