## Overview about the size of the cube

Can cube definition (in English: Cube) as a regular form of a three-dimensional, consisting of six faces, all of these square faces shape, equal size, and as the cube three-dimensional, it can be expressed by using the size, [1] defines the cube size (in English: cube volume) that the amount of vacuum inside the cube; For example, when you say that the size of a box of milk 1,728 cm 3, we need a number of cubes along the rib each 1 cm, and the number 1728 to fill this fund, [2] It should be noted that the cube size measured in cubic meter according to the Global System of Units, [3 ] in general, the size is always measured in cubic unit; For example, when the expression of the length of a cube of side 1 cm size, the output is always cubic centimeters, or cm 3, and it applies to all units. [4]

For more information about the size of the cube you can read the following article: the size of the cube law. For more information about the cube you can almost read the following article: semi-cube law.

## Law cube size

There are several laws from which to find the size of the cube, namely:

- First Law: You can find the cube size by multiplying the length, width, and height together of the cube, and as these three lengths are all equal in length, it can find the cube size by using the law as follows: [5] cube size = length of the rib × length rib × length rib, cube size = 3 rib length, symbols: h = 3; Where: [5] h: the size of the cube. For: side length of the cube. For example, if there was a length of one cubic ribs 5 cm, the size is: the size of the cube = length Aldila³ = 5³ = 5 × 5 × 5 = 125 Sm³.
- Cube size = length of the rib × rib length × length of the rib, the cube size = length of the rib 3, symbols: h = 3; Where: [5] h: the size of the cube. For: side length of the cube.
- H: the size of the cube.
- For: side length of the cube.
- For example, if there was a length of one cubic ribs 5 cm, the size is: the size of the cube = length Aldila³ = 5³ = 5 × 5 × 5 = 125 Sm³.
- Second Law: You can find the size of the cube using the length of a Oqtarh, so as follows: [6] cube size = 3√ × (cubic length of diameter / 9), and symbols: h = 3√ × (Q³ / 9); Where: S: the length of a diameter cube. H: the size of the cube.
- Cube size = 3√ × (cubic length of diameter / 9), and symbols: h = 3√ × (Q³ / 9); Where: S: the length of a diameter cube. H: the size of the cube.
- S: the length of a diameter cube.
- H: the size of the cube.

## Examples of calculating the size of the cube

- The first example: What is the size of the cube that the length of one ribs 12.5 meters? [5] Solution: the size of the length of the heel = rib Almkaab³ = 12.5³ = 1,953 cubic meters.
- Solution: the size of the length of the heel = rib Almkaab³ = 12.5³ = 1,953 cubic meters.
- The second example: the length of one cubic ribs 13 cm, what is the size? [7] Solution: cube size = rib length × length of the rib × length of the rib. Since the rib = 13 cm, the length of it can be found in size as follows: Cube = 13 × 13 × 13 size = 2,197 Sm³.
- Solution: cube size = rib length × length of the rib × length of the rib.
- Since the rib = 13 cm, the length of it can be found in size as follows: Cube = 13 × 13 × 13 size = 2,197 Sm³.
- Cube = 13 × 13 × 13 size = 2,197 Sm³.
- Third example: Notebook cubic Notes format If the length of one side of 2 cm, what is the size? [8] Solution: As all the lengths of the sides of the cube are equal, the cube size = (rib length) ³, and therefore it can be found in size as follows: Cube = 2³ = 8 Sm³ size, the size of the notebook notes.
- Solution: As all the lengths of the sides of the cube are equal, the size of the cube = (rib length) ³, and therefore it can be found in size as follows:
- Cube = 2³ = 8 Sm³ size, the size of the notebook notes.
- Example IV: If the length of each side of the cube Alrubik 5.7 cm, what is the size of this cube? [9] Solution: cube = length of Aldila³, size and therefore: the cube size = (5.7) ³ = 5.7 × 5.7 × 5.7 = 185.19 Sm³, thus, the size of the cube Alrubik is equal to 185.193 Sm³.
- Solution: cube size = length of Aldila³, and therefore: the size of the cube = (5.7) ³ = 5.7 × 5.7 × 5.7 = 185.19 Sm³, so the size of the cube Alrubik is equal to 185.193 Sm³.
- Fifth example: cube box shape internal dimensions 13 o'clock × 1 m × 1 CE, to be made of wood thickness of 5 cm, if the cost per cubic meter per 18,600 coin, what is the cost of making this fund wood note that the Fund is open from the top? [10] Solution : the cost of wood fund = fund size cubic × cost per cubic meter of wood. To find a cube size of the fund, it is a three-dimensional external (length, width, height) for this fund, as follows: Height = inner length + wood thickness = 1 m + (2 × 5 cm), equal to 1.10 m, and it should be noted that the fund was hit the thickness of the number 2, because the wood perimeter of its sides. External = 1 m + (2 × width 5 cm), equal to 1.10 m. External Height = 1 p.m. + 5cm; This is because the fund is open from the top, and is equal to 1.05 m. Since the fund will be empty from the inside, it can calculate the size as follows: Calculate the size of the external cube, the cube size = outer length of the rib Almkaab³ = (1.10) × (1.10) × (1.05) = 1.2705 cubic meters. Calculate the size of the cube procedure, which is: the size of the cube = inner length of the rib Almkaab³ = 1 × 1 × 1 = 1 m³. Size = wood used cube the size of the external - internal cube = 1.271-1 = 0.2705 cubic meters size. Calculate the cost of the wood user = 0.2705 × 18,600 = 5,031.30 currency cash.
- Solution: The cost of wood fund = fund size cubic × cost per cubic meter of wood.
- To find a cube size of the fund, it is a three-dimensional external (length, width, height) for this fund, as follows: Height = inner length + wood thickness = 1 m + (2 × 5 cm), equal to 1.10 m, and it should be noted that the fund was hit the thickness of the number 2, because the wood perimeter of its sides. External = 1 m + (2 × width 5 cm), equal to 1.10 m. External Height = 1 p.m. + 5cm; This is because the fund is open from the top, and is equal to 1.05 m.
- Height = inner length + wood thickness = 1 m + (2 × 5 cm), equal to 1.10 m, and it should be noted that the fund was hit the thickness of the number 2, because the wood perimeter of its sides.
- External = 1 m + (2 × width 5 cm), equal to 1.10 m.
- External Height = 1 p.m. + 5cm; This is because the fund is open from the top, and is equal to 1.05 m.
- Since the fund will be empty from the inside, it can calculate the size as follows: Calculate the size of the external cube, the cube size = outer length of the rib Almkaab³ = (1.10) × (1.10) × (1.05) = 1.2705 cubic meters. Calculate the size of the cube procedure, which is: the size of the cube = inner length of the rib Almkaab³ = 1 × 1 × 1 = 1 m³. Size = wood used cube the size of the external - internal cube = 1.271-1 = 0.2705 cubic meters size.

- Size = wood used cube the size of the external - internal cube = 1.271-1 = 0.2705 cubic meters size.
- Calculate the cost of the wood user = 0.2705 × 18,600 = 5,031.30 currency cash.
- Sixth example: What is the water that can be placed inside the pot cube-shaped ribs along one of the size of 2 p.m.? [7] Solution: The volume of water that can be placed inside the box = size of the cube container, and can calculate the size of the cube container using the law: Pot size = length of the rib Almkaab³ = m × 2 2 × 2 m M = 8 cubic meters, so the amount of water that can be placed inside the container is equal to 8 cubic meters.
- Solution: The volume of water that can be placed inside the box = size of the cube container, and can calculate the size of the cube container using the law:
- Pot size = length of the rib Almkaab³ = m × 2 2 × 2 m M = 8 cubic meters, so the amount of water that can be placed inside the container is equal to 8 cubic meters.
- Seventh example: What is the length of the rib cube that size equals 125 Sm³? [6] Solution: cube size = (rib length) ³, and therefore it can be found along the rib as follows: 125 = (rib length) ³, and take the cube root of the parties to produce: rib length = 5 cm.

- Example VIII: cube along a diameter of 3 cm, what is the size? [6] Solution: You can find the cube size using the following relationship: cube size = 3√ × (cubic length of diameter / 9), and is equal to: 3 = 3√ × (3³ / 9 ) = 3√3sm³.
- Solution: The cube size can be found using the following relationship: cube = 3√ × size (cubic length of diameter / 9), and is equal to: 3 = 3√ × (3³ / 9) = 3√3sm³.
- Ninth example: If the side length of the cube three times the length of the rib cube smaller than another, what is the difference between the size of both cubes? [11] to resolve this question is the following steps: Assume the side length of the small cube Q, so the size is equal to S³. Assume the length of the large cube rib 3 x, and therefore its size (3 x) ³, and equal to 27 S³. The difference between the size of both cubes = cube the size of the large / small size of the cube, so: The difference in size = 27 S³ / S³, and equal to 27. This means that the large cube larger 27 times the small cube.
- To resolve this question is the following steps: Assume the side length of the small cube Q, so the size is equal to S³. Assume the length of the large cube rib 3 x, and therefore its size (3 x) ³, and equal to 27 S³.
