How do you put a backpack in a locker with a small amount of space?

Unless the backpack (or you) changes elevation by climbing hills or stairs, the work done is zero.
Force and displacement are vectors, and so cannot be perpendicular to result in net work.

Work = Force * Distance (vertical).
It will depend on the geography of your campus. If it is flat, your backpack experiences 0 metres in vertical travel, therefore the answer is 0.
If you end up 5 meters higher than where you started, it’ll be the Force of you Backpack (in Newtons (kg * 9.81)) times 5.

Zero. Work is F dot distance, you have no vertical distance so the work is zero.
