Hence
For further, computation, if treat as a type-II region, then
For the following integrals, sketch the region of integration and express the integral in six iterated integrals:
as a type-II region, then 
, where 
is the solid in 
in the first octant bounded by the coordinate planes, the plane
and the vertical plane 
. 
is the solid in 
is the paraboloid cylinder bounded on the side by the paraboloid 
, top by the plane 
and the bottom by the 
- plane.
