Winnie-the-Pooh got a keg of honey for the winter and decided to shift honey in pots. But also on its barrel of honey there was a notorious spoon of tar. On empty pots there was an inscription "1 liter, and on a keg with honey the unclear saying "the volume of 1 cubic meter flaunted. To a bear cub with sawdust in the head not to cope with such puzzle, he should eat honey directly from a keg. But in usual life it is useful to know how many liters are located in one cubic meter. For example, if you need to fill with barrel water on the garden site. It is worth transferring cubic meters of empty barrels to water liters in pailfuls on the yoke pressing on shoulders. It becomes at once clear that it is necessary to buy the pump.
Instruction
1. Present yourself the owner of a wonderful aquarium. In one cubic meter of water it is possible to lodge a great number of sea inhabitants and to arrange the real underwater kingdom with exotic seaweed and fancy compositions from stones. However such beauty demands permanent care. Once a week when cleaning an aquarium it is necessary to drain a part of water and to add fresh water. You will not pour sea water from the crane, it is necessary to prepare necessary quantity in advance. It is necessary to define how many liters are made by the updated portion of water. All chemical reactants for maintenance of the necessary composition of water and health of inhabitants of an aquarium add to water in the quantity precisely corresponding to volume. Usually the norm of reagent on water liter is given in the instruction. Therefore it is necessary to define how many liters in cubic meter.
2. It is easy to present cubic meter in the cube form with a size of edge of one meter. The volume of such cube (V) is equal to the work of three dimensions which at a cube are identical: V=1m h1m h1m =1kub. mkubichesky meter rather large volume, for daily use smaller tanks are used considerably. Divide each edge of a cube into pieces on one centimeter. The sant prefix means "hundredth part", i.e. the centimeter makes a one hundredth part of meter. Means, each edge of a cube is divided into hundred pieces. Connect the ends of pieces on opposite edges, and each side of a cube will be divided into small squares with the party one centimeter. Count quantity of such small squares (n) on each side of a cube: n = x 100 = 10,000
3. Connect mentally tops of small squares on opposite sides of a cube, and all cube will be presented to 1 cm made of equal ranks of cubes with the party. Determine the volume of a small cube (v): v = In 1 cm x 1 cm x 1 cm = to 1 cubic smpodschitayta quantity (N) of small cubes (cubic centimeters) in a big cube (cubic meter): N = 10,000 x 100 = 1,000 000poluchayetsya that in one cubic meter one million cubic centimeters is located. One cubic centimeter rather small volume, to them unless to measure drugs or spirits.
4. But if to divide edges of cubic meter not into hundred, and into ten pieces? Each such piece is called decimeter. The dets prefix means "the tenth part". Mentally construct on these decimeter pieces cubes in cubic meter, you receive accurately delivered on ten in height ten rows of cubes with the party 1 decimeter (1 dm) on ten in each row. Each such cube has volume one cubic decimeter. This volume is also called "liter". And all in cubic meter one thousand cubes of 1 cubic dm or 1 liter is located.
5. It is easy to count that each liter contains one thousand cubic centimeters. On another the cubic centimeter is called a milliliter (ml) that is meant literally by a "thousand part of liter"
6. Remember results of a game in cubes: in one cubic meter one thousand liters, in one liter one thousand cubic centimeters or milliliters.
