Hi i am having trouble integrating this problem. can someone please show how to integrate this problem?

Use the integration capabilities of a graphing utility to approximate the work done by a press in a manufacturing process. A model for the variable force F (in pounds) and the distance X (in feet) the press moves is given. (Round your answer to one decimal place.) Force Interval F(X) = 800xx/ 125 x3 o s x s 5 ft-lb
