To lift the bag straight up takes (F · D) = (45 · 1.2) = 54 joules of energy (work).
Moving the bag horizontally 'across' gravity requires no work. It doesn't matter how far.

The total work done in lifting the 45-newton bag of mulch 1.2 meters is 54 joules. While carrying it 10 meters horizontally does not contribute to the work done due to gravity, making the total work remain at 54 joules. Therefore, only the lifting portion contributes to the work calculated.
