A drum of mass 100kg is rolled into the deck of a lorry 1.5m above a horizontal floor using a plank 4m long. Calculate the work done against gravity during the process(g=10m/s^2)?

I need the solve and the answer
work done=force ×distance
W=FD
F=ma
F=100×10=1000N
d=1.5
w=1000N×1.5
w=1,500j
work done=1,500J
W=FD
F=ma
F=100×10=1000N
d=1.5
w=1000N×1.5
w=1,500j
work done=1,500J
Is this correct?
work done=force ×distance
W=FD
F=ma
F=100×10=1000N
d=1.5
w=1000N
=1000N×1.5
=1,500j
Work Done =1,500
W=FD
F=ma
F=100×10=1000N
d=1.5
w=1000N
=1000N×1.5
=1,500j
Work Done =1,500
