Okay so I need to try to find the triple integral for the following.

Planes at x1=0, x2=0, x3=2
Area: x3=x12+22, x1≥0, x2≥0

W√(x3-x22dx

So I understand that need to find 3 integrals, the first being
020√x3-20√x32-x22 √x3-x22 dx1dx2dx3

I really dont understand how to find the upper and lower limits!?!?!?
