Homework Statement



Write out the triple integral for the volume of the solid shown in all six possible orders. Evaluate at least 2 of these integrals.


Homework Equations



I attached a picture of the figure. The front : x/2+z/5=1
right : y/4+z/5=1

The Attempt at a Solution



I really need help with the possible orders and not the actual integration.
I figured out two different orders but I'm not sure how to post them properly

Hello amalone. Welcome to PF !

You can simply describe the order in which you do the integrations, along with the limits of integration.

For example:
(From inner to outer)
Integrate over x from x = 0 to x = 1 - 2z/5 .

Integrate over y from y = 0 to y = 1 - 4z/5 .

Integrate over z from z = 0 to z = 5 .​

You could learn LaTeX and write:

\displaystyle \int_{0}^{5} \int_{0}^{1 - 4z/5} \int_{0}^{1 - 2z/5\,} dx\,dy\,dz

Thanks!
 
How about describing the orders of integration that you've found ?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
