When the space occupied by an object is three-dimensional space, the size of the space occupied is called the volume of the object.
Example 1: The volume of a wooden box is 3 cubic meters;
2: When electrolyzing water, two volumes of hydrogen and one volume of hydrogen are releasedoxygen。

China is also the first country in the world to obtain the correct formula for calculating the ball volumeSouthern DynastiesMathematician Zu ChongzhiEuropeMan was about a thousand years earlier.He also meticulously studied the art of celestial calculation (referring to astronomy and mathematics),Intensive treatmentThe calendar of the Ming Dynasty was officially issued in 510 after repeated requests from him. He also made a bronze sundial (a kind of measuring deviceshadows cast by the sunThe method of timing)ClepsydraThere are many kinds of precision observation instruments, which are adopted by later generations.

Volume formula is a formula for calculating volume, that is, a mathematical formula for calculating the volume of various geometric bodies.For example:cylinder、prism、cone, table body, sphere, ellipsoid, etc.
Volume formula: calculate various forms enclosed by planes and surfaces.
Generally speaking, a geometry is a mathematical formula for the volume of a figure formed by a face, intersection line (where the face intersects with the face), intersection point (where the intersection line intersects or where the surface converges)[3]。
The following are the calculation formulas of different graph volumes:
