Calculate a double integral with bounds?

I’m trying to obtain an answer from a double integral, but it appears to be timing out before I get my answer (it doesn’t specify that it times out, I assume it does) and returns the problem I have given it in the form of a double integral with the same bounds. I try evaluating what Mathematica gave back, and it only returns the same thing after some time has been spent. How do I work around this or change this? I attached the .nb file that I’m trying to work with.

Hello

In Integrate there is no such option like calculating time (setting the calculation time).

If Integrate give you Input then Mathematica dosen’t know the answer.

More info in attached file.

Thank you! :3 I was hoping there was a way to just to get Mathematica to perform the integration, whether it gave an actual antiderivative and plugged in the bounds afterward, or if it could use Riemann sums.

Use NIntegrate to numerically calculate an integral (via Riemann sums or a more sophisticated method). The answer has to come out to be a number though, not a symbolic formula.
