But now we wanna integrate. Our x is going from x equals one to x equals five. X equals one to x equals five. And there you have it. We have expressed the volume of that solid as a definite integral. And it's worth noting that this definite integral, if you distribute this x, if you multiply it by all of these terms, it's very solvable. You don't need a, or it's very solvable without a calculator.
