# Triple Integration

## Homework Statement

Evaluate the integral by changing the order of the integration in an appropriate way.

∫∫∫ ze-(y2+z2)dzdydx
z goes from 0 to ∞, y goes from x/6 to 3, x goes from 0 to 18

## The Attempt at a Solution

to change the integration
∫∫∫ ze-(y2+z2)dydxdz

z goes from 0 to ∞, y goes from 0 to 3, x goes from 6y to 18

I'm not sure if this is right, so if anyone could steer me in the right direction that would be very nice, thanks in advance.
