Help me out sci, im studying for a Calc 3 test i have on friday and im having trouble with a problem from the textbook (pic related)
Find the Value of the triple integral;
[math]\iiint\limits_E \,xy \mathrf{d} V\ [/math]
(my latex may suck, its the triple integral of (xy)dV on the region E). Where E is the pholyedron with vertex (0,0,0) (1,0,0) (0,2,0) and (0,0,3).
The problem im having is that the solution on the textbook is (8/3e). i really dont know how you could end up with e on the result.
thank for your help guys.

latex didnt went so bad, just ignore the red part.

oh and btw, what i did was the iterated integral where:
0<x<1
0<y<2-2x
0<z<3-(3y/2)-3x
>>
[math]\sum_{n=0}^\infty \frac 1 {n!} = e[/math]

I came up with your bounds independently

http://www.wolframalpha.com/input/?i=triple+integral+xy+dzdydx+from+x+%3D+0+to+1%2C+y+%3D+0+to+2%281-x%29%2C+z%3D+0+to+3-3x-3%2F2y

the omnisage says 1/10

Sounds like the book is wrong

And you, OP, should go to office hours and ask about the problem (especially if it was an assigned problem)
