For example, the volume of a cube is 27 cubic centimeters. According to the volume of the cube = side length × side length × side length, then we should try to see which three identical numbers are multiplied by 27, and we can use the method of decomposing the known numbers. Tried 3× 3× 3 =27, with a side length of 3 cm.

Extended data:

The cubic volume formula is:

V=a？ In the formula, a is the side length of the cube and v is the volume of the cube.

Matters needing attention in calculating cube side length by volume;

1, when calculating the side length with cube volume, be sure not to write the cube volume formula wrong, or you will not get the correct result.

2. Only by knowing the volume of the cube can we find out the side length, so we must first find out the volume of the cube.
