Explanation: 1- getting the value of the milled thickness: We are given that: 0.012 in was milled off one side 0.065 in was milled off the other sides This means that: Total milled thickness = 0.012 + 0.065 = 0.077 in
2- getting the remaining thickness: Remaining thickness = original thickness - milled thickness We have: original thickness = 1.167 in milled thickness = 0.077 in Therefore: Remaining thickness = 1.167 - 0.077 = 1.09 in
