The total work done on the object, from beginning to end of that scenario, is equal to
the change in the object's potential energy from beginning to end, which is zero.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.

a fallen treee is lifted 2.75 meters. How much work is done?
Work = force x displacementW = Fd W = 100N x 3m W = 300J 300 joules of work is done on the box.
