That is not the whole problem. To figure out how much work is done we have to know how far the box is pulled.
You did not say but I assume the box is being pulled horizontally so the force in the direction of motion is
68 cos 20 = 63.9 Newtons
The work done by the force in Joules is 63.9 times the distance moved in meters.
The magnitude of a force pulling a box 5 m at a 20 degree angle from horizontal is 68N. How much work is done on the box?
plz help me solve this!

Multiply the force component Damon provided by the 5 m distance moved and you will have the work done, in Joules
