So what's this going to be? This is going to be square root of 2 over 2 times square root of 2 over 2 is going to be 1 half, and then you're going to have another 1 half. So it's 1 fourth h squared. 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.
