Forces acting on a particle have magnitude of 14N, 7N and 7N act in the direction of vectors

Forces acting on a particle have magnitude of 14N, 7N and 7N act in the direction of vectors `6hat(i)+2hat(j)+3hat(k),3hat(i)-2hat(j) +6hat(k),2hat(i)-3hat(j)-6hat(k)` respectively. The forces remain constant while the particle is displaced from point A: (2,-1,-3) to B: (5,-1,1). Find the work done. The coordinates are specified in meters.
