Surface integrals
For the question a) ii. I was wondering if there is a quick way to do this? I worked out the surface integral for each of the 6 faces which wasn't too hard it was just quite time consuming and for 6 marks I reckon there must have been a quicker method.
The answer is just 0, if anyone could enlighten me that would be amazing. Note it says we cannot use the divergence theorem.

Does v=(x,y,z), if so is the answer not 3?

I cannot see any sensible symmetry arguments but I think most of these integrals are trivial, so it should not be that time consuming.
