The approximate nuclear radius is proportional to (
is the mass number and 
the atomic number)
Experimentally it is found that the volume of a nucleus is directly proportional to its mass number. From this it is concluded that the density of each nucleus is uniform, it does not depend on the size of the nucleus.
It the nucleus is assumed to be a sphere of radius
and its mass number is , then volume of nucleus
Thus,
Or
the radius of nucleus is directly proportional to the cube root(or 
power) of its mass number A.
