m？ Is the abbreviation of cubic meter, indicating the volume of a cube. In the international system of units, m? It is one of the commonly used unit of volume. m？ It is widely used and can be used to represent the volume of objects, liquids or gases.

Technical terms of volume and geometry. When the space occupied by an object is a three-dimensional space, the size of the space occupied is called the volume of the object. The international unit of volume system is cubic meters. One-dimensional space objects (such as straight lines) and two-dimensional space objects (such as squares) are all zero volumes.

Volume formula is a formula for calculating the volume, that is, a mathematical formula for calculating the volume of various geometric bodies (such as cylinders, prisms, cones, frustums, spheres, ellipsoids, etc.). ). The volume formula is also used for conversion between different unit of volume.

Details are as follows:

China, the first mathematician in the world who worked out the correct formula for calculating the volume of a sphere, was Zu Chongzhi in the Southern Dynasties, about a thousand years earlier than Europeans. He also carefully studied the art of celestial arithmetic (astronomical mathematics) and refined the calendar of the Ming Dynasty. After his repeated requests, it was officially promulgated on 5 10. He also made bronze sundials (an instrument for measuring the time from the shadow of the sun), clepsydra and other precision observation instruments, which were adopted by later generations.

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. 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).

The international unit of volume system is cubic meters. One-dimensional space objects (such as straight lines) and two-dimensional space objects (such as squares) are all zero volumes. The volume of a wooden box is 3 cubic meters.
