How many liters cubed

To answer this question it is necessary to understand such concepts as "l" and "cube".But for those who do not intend to finish until the end of the article, the answer to the question "How many liters in a cube or 1 cubic meter?" Will be the same - 1000 liters.Now everything is in order.

What a liter?Liter - a unit of measure.The Russian Federation has GOST 8.417-2002, which sets the designation, provides definitions and describes how to use physical units.The document lists the main units of measurement of the International System of SI and their derivatives.The main concerns meter.This is the path traveled by light in vacuum during the period of time that is equal to 1/299792458 seconds.Such values ​​as the area or volume, measured in derived units: square meter (m2) and the cubic meter (m3).Table 6 GOST 8.414-2002 number listed units are not included in the SI system and allows for use without restrictions.By Common Units applies liter (L).It is used for measuring physical quantities such as the v

olume or capacity.1 liter = 1 dm = 10.3 m³.Thus, we can calculate how many liters of water in the cube.Since 1 m contains 10 dm and 1 m³ = 1 m • 1 m • 1 m, the 1 m³ dm = 10 • 10 • 10 dm dm dm = 1000 = 1000 liters.

with the word "cube" that took place from the Greek «kybos», the situation is more complicated as it has several meanings.

  1. They designated geometric body, which is a regular polyhedron - geksaeder, each face (of six) which is a square.If the side of the square is equal to 1 m, it is the body occupies a volume of 1 m³ or 1,000 liters.But if there is another side of the edge, for example, 3 m, then the question "How many liters in a cube?" The answer will be different.This polyhedron occupies a volume of 3 m • 3 m • 3 m = 9 m³ = 9,000 liters.
  2. Colloquial "cube" to be understood as a volume of 1 cubic meter.Suitable, for example, to evaluate the amount or volume of soil excavated pumped liquid.If you ask: "Water Cube - how many liters?", In this case, the answer follows from the GOST 8.417-2002, which determines the ratio of units, ie cubic meters of water - is 1 m³ = 1000 liters.
  3. In mathematics, the word "cube" is the degree of the number, which must be multiplied by itself three times.In this case, the question "How many liters in a cube?" Inappropriate.
  4. In some manufacturing processes (e.g., in power industry, chemical industry) and household word "cube" may denote an apparatus in which the boiling liquid for evaporation or distillation (distillation).These devices often have a form different from a regular polyhedron (hexahedron).Typically, they are cylindrical.As in this case, to calculate how many liters cubed?Using the ratio of units, multiply the apparatus in a known volume of cubic meters in 1000, the result is the its volume in liters.

To convert the volume, expressed in other units, such as cubic centimeters, millimeters or kilometers, should go back to GOST 8.417-2002.More precisely, to his table number 7, which defines the rules of education symbols and names of decimal multiples and sub-units of physical quantities in the SI system.For these purposes consoles (there are indicated in Table 20 pieces), which correspond to a decimal factor.When added to the basic unit of a specific prefix (such as iota, peta, giga, pounds, deck, Santa, Milli and others), it is clear on what decimal multiplier multiply the basic value to get her to fold the unit.

prefix "kilo" corresponds to the factor 10³ (or 1000)."Santi» - 10² (or 100)."Millie" - 10-³ (or 1/1000).As an example, we can calculate how many liters in a cube (regular polyhedra), the side faces of which equals 0.3 kilometers (km), 3 centimeters (cm) or 3 millimeters (mm).

  1. For the first case: 0.3 km • 0,3 • 0,3 km km = 0,009 cu km.Since 1 km = 1000 m, is 0,009 cubic kilometers = 9,000,000 m³ = 9,000,000,000 liters.
  2. For the second case: 3 cm • 3 cm • 3 cm = 9 cc.Since 1 cm = 1/100 m, then 9 cm³ = 0.000009 m³ = 0.009 liter.For such volumes are commonly used unit of measurement known milliliter (ml) of 1 cc or 10-³ l.
  3. For the third case 3 mm • 3 mm • 3 mm = 9 mm³.Since 1 mm = 1/1000 th, the 9 mm³ = 0.000000009 m³ = 0.000009 liter.Perform any actions with these numbers is inconvenient, so use a unit of measurement known microliter (l), which is equal to 10-³ ml or 6.10 l.

Obviously, to correctly answer the question "How many liters in a cube?" Or for any unit conversion is necessary to use an interstate standard GOST 8.417-2002 (accepted by ten countries - members of the CIS).The presence in his designation of a figure eight with a dot indicating that it belongs to metrology (the science by which traceability is ensured and achieved the required accuracy).For information: standards, the designation of which is the number twelve with the point, include requirements to ensure safe working conditions.
