Cubes of cuboids = ABC Cubes of a cube = a 3；; The cube of a sphere is 4 π r 3, where A, B and C are the side lengths of a cuboid, a cube and a sphere, respectively. ?
Some geometric figures can't be measured directly and are not easy to calculate, so we need to estimate their volumes. For example, if a container holds water, the volume of water in the container is estimated, and the container is often filled with water, so it is necessary to measure the volume of spilled water.
Cubes are the accumulation of strength. In mathematics, power is a mathematical operation. Divide the power of a number to get a new number. For example, A =a*a cube, B =b*b cube, and C =c*c * C cube.
If carry, the unit of cube takes the unit of square root, one tenth takes one tenth of the square root, one percent takes one percent of the square root, and so on. ?
Characteristics of error formula:
1, claiming to be scientific, is vague and lacks specific weights and measures.
2. Operation definitions (for example, public variables, objects that belong to or can be checked by outsiders) cannot be used.
3, can not meet the principle of simplicity, that is, when many variables appear, can not get the answer from the simplest way.
4. Use vague language and a lot of technical terms to make the article look scientific.
5. Lack of boundary conditions: rigorous scientific theory clearly defines in a limited scope, and clearly points out when and where the prediction phenomenon is applicable and when and where it is not applicable.
