# Another vector problem

## Homework Statement

Consider two elementary parallelopiped in tandem (i.e. joined side by side).Calculate the flux of a vector field F through these two parallelopiped and arrive at Gauss's divergence theorem

## The Attempt at a Solution

All standard textbooks contain the proof with a single parallelopiped.I do not understand in what way this problem is going to be different.Please help if some new trick is to be employed
