After more than two thousand years of research and demonstration by our forefathers, it has been established that a cubic equation with rational coefficients has no rational root, and then a line segment with a length equal to any real root cannot be constructed using only a ruler. Based on this, it is concluded that "cubic product belongs to ruler drawing and cannot be a problem." This drawing does not involve a cubic equation, but through exploration, it is found that the edge ratio of a given cube to a double cube is fixed. If the ratio of two edges can be found, it is possible to make a double cube of a given cube with a given edge. If we need to find the ratio of the edge length of a known cube to the edge length of a double cube, we need to use the edge length of the known cube to determine the edge length of the double cube, and then construct the double cube based on the dimensions of the known cube.
