I can't straight up give you the solution/answer as that is against TSR rules but first I think you should consider the equation for work done.
Do you know what it is?

resolve some forces and then use the equation for work done

I was having trouble with which displacements to take for the 100N forces actually, the work done for 70N and 30N is 0J as the box doesn't move in those directions. The work done by 100N force along the slope is 100*0.5=50J? And for the weight should the displacement be 0.5sin45? If so, the Work done amounts to 35.4J.
