Answer:

I found: #~~7596J#

Explanation:

I think that you can use the work done against gravity as:
#W_g=mgh#
with your data:
#W_g=337*9.8*2.3~~7596J#

You can also try using the force needed to push the crate (equal to the #y# component of the weight) and the distance and you'll get the same result.
