[Multivariable Calculus] Flux and Maple Program

1. The problem statement, all variables and given/known data
It would help if you guys had access to Maple
Anyways here is the problem: http://poibella.org/calc3f11/wp-cont..._calc_F_11.pdf
It is on question 12 asking for flux and the questions after that.


2. Relevant equations
In the link


3. The attempt at a solution
So for the s and t ranges I got -0.01..0.01 for both of them. Also on the graph imagine a plane that spans from -0.04 to 0.04 on the y axis, -0.01 to 0.01 on the z axis and x=4. Someone told me to compute the cross product of the length of the sides, and then dot it with <4,-3,0>. However I'm not sure if this is correct when finding flux.
From there, how do i answer question 13 and 14?
