How to calculate the cube, find the formula, how to calculate the cube formula

The cube of the cuboid is the volume: length, width, and height;

Cube. The cube is the volume: edge length x edge length x edge length.

In terms of graphics, a cubic is a measure of the volume of an object, such as cubic meters, cubic decimeters, cubic centimeters.

and other commonly used units, the steps are as follows:

1) Find the cube.

The edge is long. 2) Ridge length = volume (Note: If the edge length unit is centimeters, the volume unit.

is a cubic centimeter, written cm; If the unit of edge length is meters, the unit of volume is cubic meters, write m, and so on. ）

The volume of a cube with a length of one meter on each side is equal to one cubic meter.

Conversion relationship 1 cubic decimeter = cubic meter.

1 cubic centimeter = 001 cubic meter.

1 square meter (public square) = 1 cubic meter.

1 cubic meter abbot = 1 cubic meter.

1 cubic meter = 0 cubic meters.

1 cubic yard = 6 cubic meters.

1 cubic foot = 317 cubic meters.

1 cubic inch = 703 10 (-5) cubic meters <>

A cube is the multiplication of three identical pieces of data. In Excel, the cubic calculation method generally consists of two ways.

1. General operation method, formula = data cell * data cell * data cell.

2. Function method, formula = power (data cell, 3). The formula for calculating the cube is: cuboid volume = length, width and height; Cube volume = edge length x edge length x edge length. The cube of a number is equal to the number itself multiplied three times in a row.

Hello classmates, the cubic formula is as follows.

Cubes and formulas.

a^3+b^3=(a+b)^3-3ab(a+b)

a+b)[(a+b)^2-3ab]

a+b)(a^2+b^2+2ab-3ab)

a+b)(a^2+b^2-ab)

a+b)(a^2-ab+b^2)。

2. Cubic deviation formula.

In the cube sum formula "a 3 + b 3 = (a + b) (a 2-ab + b 2)", replace "b" with "(-b)" to obtain:

a^3+(-b)^3=[a+(-b)][a^2-a(-b)+(b)^2]

a-b)(a^2+ab+b^2)

3. Complete cube sum formula.

a+b)^3=(a+b)(a+b)^2

a+b)(a^2+2ab+b^2)

a^3+2(a^2)b+a(b^2)+(a^2)b+2a(b^2)+b^3

a^3+3(a^2)b+3a(b^2)+b^3。

Note: The perfect sum of squares formula: (a+b) 2=a 2+2ab+b 2.

4. The perfect cubic variance formula.

In the perfect cube sum formula "(a+b) 3=a 3+3(a 2)b+3a(b 2)+b 3", replace "b" with "(-b)" to obtain:

a+(-b)]^3=a^3+3(a^2)(-b)+3a[(-b)^2]+(b)^3

a^3-3(a^2)b+3a(b^2)-b^3。

The cube of a cuboid cube: length, width, height.

Cylindrical: The base area is high.

Cone: Base area height 3

The cubic volume of a rectangle: length, width, height.

The cubic volume of a cylindrical shape: the base area is high.

The cubic volume of a square: side length x side length x side length.

To calculate the cube, it is the length multiplied by the width multiplied by the depth.

How to calculate the cube length of a rectangle multiplied by width multiplied by height. For example, the cube of the earth is calculated as a pile of soil that is one meter wide and two meters long and three meters high, and the volume level of the mound is 1 2 3 = 6 cubic meters.

Question in**, what cube are you asking, or what is the cube formula? The cube formula has a cube sum formula and a cube difference formula, so you have to send it in to give you a formula about the cube.

The cubic formula is used to calculate the volume in three-dimensional space. The cubic formula is: volume = a (cube) where a is the length of one side of the cube, i.e. the size of one face of the cube.

For example, if one of the faces of a cube is square and the side length is a = 3, then the volume of the cube is 3 =9. If one of the slip curves of the cube is rectangular with a = 4 in length and b = 2 in width, then the volume of this cluster of cubes is (4 2) 16 =64. It is important to note that the cubic formula only applies to objects with a regular cube structure, such as a cube or a cuboid.

For objects of other shapes, other formulas are required to calculate the volume.

Summary. The formula for calculating cubic meters is: v=a·a·a; Cubic meters are units of volume and are used to calculate volumes, for example, if the side length of a cube is 1 meter, then the volume of the cube is 1 meter 1 meter 1 meter = 1 cubic meter. A cubic meter is a unit of volume.

Further reading: What is the cubic variance formula.

Cuvariance Formula:

a^3 - b^3 = a-b) (a^2+ab+b^2)。

Derivation process:1The proof is as follows:

a-b)^3=a^3-3a^2b+3ab^2-b^3

So a 3-b 3=(a-b) 3-[-3(a 2)b+3ab 2]=(a-b)(a-b) 2+3ab(a-b).

a-b)(a^2-2ab+b^2+3ab)=(a-b)(a^2+ab+b^2)

2.The proof is as follows: a 3-b 3=a 3-a 2*b-b 3+a 2*b

a^2(a-b)+b(a^2-b^2)=a^2(a-b)+b(a+b)(a-b)=

a-b)[a^2+b(a+b)]=a-b)(a^2+ab+b^2)

Corollary: Similarly, we have cubes and formulas and their generalizations:

1) a^3+b^3=(a+b)(a^2-ab+b^2)；

2) a^n+b^n=(a+b)[a^(n-1)-a^(n-2)×b+..1)^(r-1)×a^(n-r)×b^(r-1)+.b (n-1)] (n is an odd number greater than zero, r is the ordinal number of the terms in parentheses) (the sum of the powers of the terms in the following parentheses is n-1).

a n is the nth power of a.

Summary. Then minus 40

What is it like, can you show me so that I can calculate better.

The middle is a 40cm square, friendly and disadvantaged high bread brigade stove stone, good town clan wrapped after the 4 sides are each 83cm long, how many cubic meters of stone are high.

It is also a pillar in a mess, each of the four sides is 40 centimeters of Yuyuan, high meters, now wrap it with stones, after wrapping the four sides of each collapse file is 83cm, the height is also meters, the same height, now ask how many cubic meters of stones.

You seem to have counted all the pillars and cubes.

Isn't that so.

No. To subtract the stake cube.

Then minus 40

The two methods can be calculated, but the results are not the same
