Given:
D= 4xy ax + 2(x2 + y2) ay + 4yzaz nC/m2 bounded by the planes x=0 and 2, y= 0 and 3, z= 0 and 5.
Required:
i) Total flux crossing the surfaces of the rectangular paralelipiped.
ii) Total charge within the rectangular paralelipiped
Solution:
Given

let us compare this with the following equation

Then, we have



This parallelepiped is enclosed by the following planes at



(i)
Before calculating the flux, we will see which planes will contribute the total flux


This means, out of six planes only four planes will contribute to the total flux





Therefore the total flux is 
(ii)
Total charge inclosed in the parallelopiped is
