Incredible explanation but there is a calculus mistake in the dot product of the second integral

Just a heads up, 3 of your videos on Surface Integrals aren't in your multivariable calculus playlist!! I was quite confused when the playlist jumped from surface areas to Stoke's theorem. Fantastic videos though, they're incredibly helpful.

For your last example, the normal is actually pointing in the wrong direction since you have positive 1 as your z component

About the second surface integral, I got 12 pi as answer, dunno if it's correct, but in the video there's some mistakes in the dot product

z component should be negative if the normal via the cross product is to point outward

I've got -8π via the divergence thm
