I have some homework thats due tomorrow and having a lot of trouble with this one problem

the problem states evaluate (triple integral of E) of xyz dV where E lies under the plane z=1+x+y and above the region in the xy plane bounded by the curves y=sqrt(x), y=0 and x=1

my main issue is the z boundary, the answer in the back is 66/28 but I cannot even come close to that with the work I do, can anyone help?
