Just use the equation W=F*X since it is a flat surface. There is no friction that would counteract and make this more complex. The only forces acting on the block would be the tension.
In short, the work would be 300N*m or 300J, assuming that the problem is as simple as mentioned.
A 5kg block is being pulled on a horizontal frictionless surface. The tension in the string is 30N. What is the total work done on the block as it moves a distance of 10 meters?
Thank you very much!

w=f*X
since it horizonal they won,t be friction
since it horizonal they won,t be friction
