Work = (strength of force) x (distance)
We can't calculate the work you did, because we don't know
how much force you used to push the object.
If the object is on wheels, on ice, or on an air hockey table,
then you could move it with a very small force.
If the object is sliding on gravel, then you need a large force
to move it.
The amount of work you do depends on the strength of the force
you use, not necessarily on the weight of the object you move.
