my first 3-d problem, using integrals somehow. (calc 1)

So the problem is easy to understand, I think (I know what I'm supposed to find, I see what I'm being asked to do), but I have no idea of how to go about approaching this stuff.

I won't give you the whole answer, just point you in the right direction. (Okay, I lied. I've given you most of the answer, you just have to put it together to get the actual formulaYou've done Riemann and other rectangular sums as a lead-up to why integrals give you the area under a curve, right? In that case you were taking the sum of the areas of an infinite number of infinitessimally skinny rectangles, each with a height of f(x) and a width of dx

I think that's one of the best descriptions of this topic I've seen.

thanks! that's very clear.
