Planes at x

_{1}=0, x

_{2}=0, x

_{3}=2

Area: x

_{3}=x

_{1}

^{2}+

_{2}

^{2}, x

_{1}≥0, x

_{2}≥0

∫

_{W}√(x

_{3}-x

_{2}

^{2}dx

So I understand that need to find 3 integrals, the first being

∫

_{0}

^{2}∫

_{0}

^{√x3-2}∫

_{0}

^{√x32-x22}√x

_{3}-x

_{2}

^{2}dx

_{1}dx

_{2}dx

_{3}

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