Please don't use the divergence theorem
we cant find as you said
since F(x,y,z) = del f where f is also a function of 3 variables
but you mentioned f(x,y) in 2 variables which is not possible with your function
we have to use divergence theorem and get the solution as follows.
I hope you understand if u have any more doubts comment below or discuss with your professor.
