Before going to stackexchange you should consider if a square root transformation is appropriate for the model that you are trying to estimate. If you do so, you may be able to interpret the coefficients yourself. If no explanation is obvious you probably should not be using a square root transformation.
Also you might google "square root transformation regression" and you will find several useful links.
