HI, Dr.Clark im just confused with the value that we get after computing the triple integral. In the 1st example, we get 3/2, so what does this actually means? It is a scalar right?

I've read online where a positive number means positive divergence where larger arrow implies greater magnitude, but here we are required to calculate the surface? So does the value 3/2 has a value like m^2 or something? Im new to this div, curl thing as i am about to enter my Analysis 2 class.

Why did you write the additional 'r' at 6:31 ?
