A 1200N force is applied parallel to a horizontal surface. It pushes an 80N box 10m across the surface. What work is done? What power is dissipated in 3 minutes?

What i did for this one is subtract the 80N force from the 1200N force and multiply it by 10m because W= FxD

1200-80=1120x10m=11200J, problem is im not sure if im supposed to subtract the 80N force of the box. For power, i did 11200/180s=62.22 watts, but im not sure if thats just power or if its power dissipated

any help would be greatly appreciated, thanks
