1. Add water or other liquid to the graduated container, and then put the stone into the water. A graduated liquid is a volume, provided that the stone will not absorb water or other liquids.
If you know the density of the stone, weigh it, divide it and it will come out. Third, put this stone on the balance, and put the regular small stone on the other end of the balance. When it is equal to his weight, calculate that the volume of all small stones is equal to the volume of irregular stones.
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 computing (referring to astronomical mathematics) and mastered the calendar of the Ming Dynasty.
After his repeated requests, it was officially promulgated in May10, and a variety of precision observation instruments, such as bronze sundial (an instrument for measuring the sun's shadow to time) and clepsydra, were adopted by later generations.
