2. Cube volume = side length × side length × side length.

3. Volume of cylinder (circle) = pi × (bottom radius× bottom radius )× height.

4. Cone (circle) volume =πx bottom radius x bottom radius x height /3.

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

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. Volume formula: calculate various planes and surfaces.

Generally speaking, geometry is a mathematical formula of the volume of a graph composed of faces, intersection lines (intersection points of faces) and intersection points (intersection points of intersection lines or convergence points of surfaces).

Extended data:

Solid geometry can be divided into the following categories:

1, cylinder: including cylinder and prism. Prisms can be divided into straight prisms and oblique prisms, and can be divided into triangular prisms, quadrangular prisms and n prisms according to the number of sides of the bottom; The volume of the prism is equal to the area of the bottom multiplied by the height, that is, V = SH.

2. Cones: including cones and pyramids, which are divided into triangular pyramids, quadrangular pyramids and N pyramids.

3. Rotating body: including cylinder, frustum, cone, sphere, spherical crown, bow ring, circular ring, dike ring, fan ring, jujube stone, etc.

4. Section: including frustum, frustum, truncated cylinder, truncated prism, truncated cone, spherical crown, spherical notch, etc. Its surface area and volume are generally solved by digital addition and subtraction.
