It doesn't give the exact cube root of two, but a ghost nonexisting number that tries hopelessly to replace a fictional number assumed existing in mind only but always and forever unsuccessfully for sure, otherwise state it exactly as requested
However, we are very familiar with that carpenter'S skill (even before BC), WHERE he can easily make a cube with two unit volume to a very good degree of accuracy for sure
