A hydraulic excavator is excavating the basement for a large building. Heaped bucket capacity is 1.5 cu yd. The material is common earth with a bucket fill factor of 0.90. Job efficiency is 50 min/hour. The machine’s maximum depth of cut is 15 ft, and the average digging depth is 13 ft. The average swing angle is 180 degrees. Estimate the hourly production in loose measure.  Use the tables below for reference.    

Compute the area enclosed by the cross-section and roadbed template shown in the figure below.  All units are in feet, convert the final answer to yards
