the number of teeth times the RPM gives the number of teeth for minite that cuts in labor. teeth 12×350 = 4200 or slices for minite. Each tooth takes a bite of .025 inch to 4200teeth per minute that takes .025 for each tooth is 4200x.025 = 105 inches covered each minite. 136 inches in length were divided by 105inches for minites of minite = 1295 for cutting.
