God's favorite form of torture for Calculus III college students. Typically, triple integrals are not even touched by most colleges as students would sooner pass out than shoulder the immense pain of evaluating such nonsense.
With double integrals, you do an integral twice but square the pain.

Before I entered pre-med, I thought I learned the true meaning of pain in my Calculus III class--double integrals.
