The volume of liquid can be measured directly and the volume of solid can be measured indirectly by measuring cylinder or measuring cup (exhaust method); Regular solids can also be measured with a scale, and then calculated with mathematical volume formula. Volume, geometry terms. When the space occupied by an object is three-dimensional space, the size of the space occupied is called the volume of the object.
Volume formula is a formula for calculating volume, that is, a mathematical formula for calculating the volume of various geometric objects (such as cylinder, prism, cone, table, sphere, ellipsoid, etc.). Volume formula is also a formula used for conversion between different volume units.
Zu Chongzhi, a mathematician in the Southern Dynasty, was the first in China and the world to arrive at the correct formula for calculating the volume of the ball, about a thousand years earlier than Europeans. He also meticulously studied the celestial arithmetic (referring to astronomy and mathematics) and refined the Ming calendar. After repeated requests, it was officially issued in 510. He also made a variety of precision observation instruments, such as the copper sundial (an instrument that measures time by measuring the shadow of the sun), clepsydra, and so on, which were adopted by later generations.
Volume, the size of the space occupied by an object is called the volume of the object. The SI system of volume is cubic meters. The volume of a solid object is a numerical value used to describe the space occupied by the object in three-dimensional space. One dimensional space objects (such as lines) and two dimensional space objects (such as squares) have zero volume in three-dimensional space.
