Unit of volume, which is equal to the volume of a cube with one meter on one side, is equal to 1 m3. Cubic meter capacity: it is equivalent to the volume of a cube whose length, width and height are all equal to 1 meter.

The mathematical definition of a cube is as follows:

1 and cube are also called cubes, and the product of three identical numbers is called the cube of this number. For example, 5×5×5 is called the cube of 5, and it is recorded as 5? .

2, quantifier, used for volume, generally refers to cubic meters.

3. In terms of graphics, cubes are units for measuring the volume of objects, such as cubic meters, cubic decimeters, cubic centimeters and other commonly used units.

4. A cube is equal to its own number only 1, 0,-1.

5. The cube of positive number is positive number, the cube of 0 is 0, and the cube of negative number is negative number. Extension: odd powers of negative numbers are all negative numbers.

China was also the first mathematician in the world, Zu Chongzhi, who calculated the correct formula for the volume of a sphere, 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.

The unit conversion of volume is as follows:

1 cubic decimeter = 1000 cubic centimeter = 100000 cubic millimeter = 1 liter = 1000 ml =0.06 1 cubic inch.

1 cm3 = 1000 cm3 = 1 ml =0.00006 1 cubic inch.

1 m3 = 1000 cubic decimeter = 1000000 cubic centimeter = 10000000 cubic millimeter =0.353 cubic foot = 1.3079 cubic yard.

1 cubic inch =0.0 16387 cubic decimeter = 16.387 cubic centimeter = 16387 cubic millimeter.

1 cubic foot =28.3 cubic decimeter = 28,300 cubic centimeters = 28,300,000 cubic millimeters.

1 cubic yard =27 cubic feet =0.7646 cubic meter = 164.6 cubic decimeter = 164600 cubic centimeter = 16460000 cubic millimeter.

1 cubic foot = 3 1. 143 bushels (English) = 32. 143 bushels (American)

1 gallon (American) = 0.0054 1 18 m3 = 0.8364 1845 gallon (British).
