The first thing we have to do is figure out the general equations for the lines that create the trapezoid.

Now we have the general equations for out trapezoid, now we need to plug in our transformations into these equations.

So our region is a rectangle given by ,

Next we need to calculate the Jacobian.

Now we can put the integral together.

In order to convert to spherical coordinates , we need to remember the conversion equations.

Now lets apply this to our problem.
