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. So let's say y max is 1,500, and if for whatever reason our graph doesn't fit in there, then maybe we can make our y max even larger. So I think this is going to be a decent range. Now let's actually input the function itself.
