Volume is a technical term of geometry, and it is the size of the space occupied by an object. The international unit of volume system is cubic meters.

Volume formula of common graphics:

1, cuboid: (cuboid volume = length× width× height)

2. Cube: (Cube volume = side length × side length × side length)

3. Cylinder (perfect circle): the volume of cylinder (perfect circle) = pi × (bottom radius× bottom radius )× height.

The volume of the above three-dimensional figure can be summarized as: (bottom area × height)

4. Cone (perfect circle): volume of cone (perfect circle) = pi × bottom radius× bottom radius× height /3.

5. pyramid:? Pyramid product = bottom area × height /3

6. Sphere: Sphere volume = 4/3(π× radius cube)

Area is the size of a plane figure.

Area formula of common figures:

1, rectangle: {rectangle area = length× width}

2. Square: {Square area = side length × side length}

3. Parallelogram: {parallelogram area = base × height}

4. Triangle: {Triangle area = base × height ÷2}

5. Trapezoid: {Trapezoid area = (upper bottom+lower bottom) × height ÷2}

6. Circle (perfect circle): {area of circle (perfect circle) = π× radius× radius}

7. ring:? {Circular (outer ring) area = {pi × (outer ring radius 2- inner ring radius 2)}

8. Sector: {circle (sector) area = π× radius× radius× sector angle /360}

Extended data:

Commonly used unit of volume: cubic meter, cubic decimeter, cubic centimeter and cubic millimeter.

Volume formula is a formula for calculating volume, that is, a mathematical formula for calculating the volume of various geometric shapes. For example: cylinder, prism, cone, platform, sphere, ellipsoid, etc.

Common units of area: square meter, square decimeter and square centimeter, which are recognized units of area and can be expressed as (m? ，dm？ ，cm？ )。

Conversion of commonly used unit of volume:

1 cubic decimeter = 1000 cubic centimeter = 100000 cubic millimeter = 1 liter = 1000 ml =0.06 1 cubic inch.

1 cm3 = 1000 cm3 = 1 ml =0.00006 1 cubic inch.

1 m3 = 1000 cubic decimeter = 1000000 cubic centimeter = 10000000 cubic millimeter =0.353 cubic foot = 1.3079 cubic yard.

1 cubic inch =0.0 16387 cubic decimeter = 16.387 cubic centimeter = 16387 cubic millimeter.

Conversion of public area units:

1 ㎡( 1㎡)= 100dm？ (100 square decimeter) = 10000 cm? ( 10000 cm2)= 1000000mm？ (1000000 mm2)

1m2 = 0.0001hectare =0.00000 1km? (0.000001km2) = 0.01mu =0.00 15 mu.
