Did I do that right? This is, yes, it's going to be 2 over 4, which is 1 half, and then times another 1 half is 1 fourth h squared is the area. Now what's going to be the volume of each of these triangles? Well, the volume of each of these triangles right over here, the volume is just going to be our area times dx, or it's just going to be 1 fourth h squared times our depth, dx. And so if we just integrated a bunch of these from our x equals 0 all the way to x equals c, we essentially have our volume of the entire figure. So how could we write that? So we want to write, we want to essentially define the volume of the figure, and we're kind of in the home stretch here.
