Why does the work of expansion at a constant pressure use volume for the integral?

Because if pressure is not changing the only thing changing is volume

Work of expansion at constant pressure has to incorporate volume because expansion is a change in volume. So, to calculate the work needed to change the volume,the integral should involve the volumes.
