Volume calculation formula

The formula for calculating volume is the formula for calculating volume. That is, a mathematical formula for calculating the volume of various geometric shapes.

Column:

General formula: V=Sh(S is the bottom area and h is the height)

Cylinder: V=πr? H(r represents the radius of the bottom circle and H represents the height of the cylinder)

Prism: (V=Sh bottom area × height)

Cuboid: V=abc(a, B and C represent the length, width and height of the cuboid respectively).

Cube: V=a? (A stands for the side length of the cube)

Cone:

General formula: V= 1/3Sh(S is the bottom area and h is the height).

Cone: V= 1/3πr？ H(r is the bottom radius and h is the height)

Triangular pyramid: V= 1/6|a? b？ c？ +b？ c？ Answer? +c？ Answer? b？ -a？ c？ b？ -B? Answer? c？ -c？ b？ Answer? Triangular pyramid is the most common and basic figure in three-dimensional space, just like triangle in two-dimensional space. Coordinate A(a? Answer? Answer? )

B(b？ b？ b？ )C(c？ c？ c？ ) o is the origin

Ellipsoid:

Ellipsoid volume formula: 4/3πabc

Units and conversion:

Cubic meters m?

Cubic decimeter Deutsche mark

Cubic centimeter cm?

Cubic millimeter mm?

1 m3 = 10？ Cubic decimeter = 10? Cubic centimeter = 10? cubic millimeter

1 liter = 1 cubic decimeter = 10? ML = 10？ Cubic centimeter = 10? cubic millimeter

Cubic feet (cubic feet /CUF/CUFT)

1 cubic feet = 1 (feet? ) =0.0283 cubic meters (m? ) =28.3 17 liters (liters) =28.3 17 cubic decimeter (dm? )= 283 17ml = 283 17 cm3(cm？ )=2.83 17× 10?

1 cubic inch (in) = 16+0 cubic centimeter (cm? )

1 acre foot = 1234 cubic meters (m? )

1 bbl)= 0. 159 m3 (m？ ) = 42 US gallons

1 gallon = 3.785 liters

1 American quart = 0.946 liter

1 American pint (pt)= 0.473 liter (l)

1 Meguiar's = 0. 1 18 liters (liter)

1 gallon = 4.546 liters

Volume conversion formula:

Computer scientist Nicklaus Voss put forward this formula: program = algorithm+data structure. Looking at the data types in C language, we will find that different data types occupy different memory space.

8 bits = 1 byte (b)

1024 bytes = 1 kilobytes (KB)

1024 kilobytes = 1 megabyte (MB)

1024 MB = 1 GB

1024 gigabytes = 1tb

1024 terabytes = 1 gigabyte (PB)

1024 Pb = 1 EB

Perimeter formula:

The circumference of a rectangle = (length and width) ×2

Circumference of a square = side length ×4

Circumference = π× diameter = 2×π× radius

Area formula:

Area of rectangle = length × width

Area of a square = side length × side length

Area of triangle = base × height ÷2

Area of parallelogram = base × height

Trapezoidal area = (upper bottom and lower bottom) × height ÷2

Area of circle = π× radius 2

Lateral area of a cylinder: the lateral area of a cylinder is equal to the perimeter of the bottom multiplied by the height.

Surface area of cylinder: surface area of cylinder = bottom area transverse area.

Ancient unit of measurement

1 stone = 10 barrel

1 = Originally 10, it was changed to 5.

1 barrel = 10 liter

1 =0.5

1 l = 10.

Brief introduction of computer scientist:

Nicklaus Voss was born in winterthur on February 65438, 0934. His father Walter is a geography professor. As a child, Voss was keen on using his hands and brains, and assembling airplane models was his greatest hobby. After graduating from high school, Voss entered the world-famous Zurich Institute of Technology and obtained a bachelor's degree from 65438 to 0958. After that, he crossed the Atlantic to the University of Levi in Canada for further study, pursuing higher academic research, and finally obtained the master's degree of 1960. Later, he moved to California again and entered the University of California, Berkeley, where he received his doctorate at 1963.

Anyone who has learned a little computer knowledge probably knows the very famous formula "Data Structure Ten Algorithms = Program". Swiss computer scientist Nicklaus Wurth put forward this formula and used it as the title of one of his monographs. He won the Turing Award of 1984 because he invented many far-reaching programming languages and put forward the revolutionary concept of structured programming. He is the only Swiss scholar who has won this honor so far.

Voss is a man with strong patriotic feelings. After becoming famous, he refused to stay at Stanford University and returned to the motherland on 1967. He first taught at the University of Zurich, but returned to his alma mater, Zurich Institute of Technology, the following year. Here, he first designed and implemented PASCAL language, and successfully developed it on CDC 6600. PASCAL has made many innovations in data structure and process control structure. For the former, PASCAL adds character type, subdomain type, record structure type, file type, set type and pointer type besides general integer, real number and Boolean data. For the over-control structure, in addition to retaining the unconditionally transferred GOTO statement, various control structures such as if-then-else, case, while, repeat, for, etc. are added, and with statements are also allowed to be used for compound statements and components that handle record variables. It can be said that the data structure and control structure commonly used in modern programming languages are mostly based on PASCAL language, so they are of great milestone significance in the development history of programming languages.
