And so if we wanna figure out the volume of this little section right over here, we'd multiply x times this. And then we would multiply that times an infinitesimally small depth, a dx. And then we can just integrate from x equals one to x equals five. So let's do that. The volume of just this little slice over here is going to be the base, which is negative x squared plus six x minus five times the height, times x, times the depth, times dx. And then what we wanna do is we wanna sum up all of these. And so you could imagine right over here, you would have, or like right over here, you would have a cross section that looks like this.
