Answer:
 960J
Explanation:
Given parameters: 
Force  = 120N 
Distance = 8m 
Unknown: 
Work required  = ? 
Solution: 
The work done by a body is the force applied to move a body in a specific direction. 
  Work done  = Force x distance 
Insert the parameters and solve; 
   Work done  = 120  x  8  = 960J
