So that would be, did I do that right? Yeah, 20 minus 2 times 5, so that would be 10. And then times 30 minus 2 times 5, which would be 20. So it would be 5 times 10 times 20. So you'd get a volume of 1,000 cubic inches, and I just randomly picked the number 5. Let me give my maximum y value a little higher than that, just in case that that isn't the maximum value. I just randomly picked.
