Several nuclear charge radii had been calculated based on the law of A(1/3) and isopin dependence Z(1/3) formula which had been used to describe the charge radii data. It is achieved that the isospin dependence Z(1/3) formula is superior to the generally accepted A(1/3) law through mean root square deviation analysis, that is, the Z(1/3) formula is more effective to describe the charge radii data.
