Homework Statement



Use a triple integral to find the volume of the solid enclosed by the cylinder z=y2 and the planes x=0, x=6, and z=16. Set up the integral in rectangular coordinates and work it out in any coordinates.

Homework Equations


The Attempt at a Solution



I set up the triple integral using these orders of integration:

D = { (x,y,z) | 0 < x < 6, -4 < y < 4, y2 < z < 16 }

And I obtained an answer of 512. I just wanted to make sure that I did all the work correctly, and that someone more experienced could say if it is correct.
Thank you!

Your limits look good so if you didn't make any arithmetic mistakes it should be correct.

Thank you very much, Mr Kurtz!
 
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...
