    Simply calculate the volumes of the trench on each day and subtract. On the first day, it had a volume of 3x5x12=180 cubic feet. On the second day, it was extended by 8 feet, so the length is now 20 feet. 3x5x20=300 cubic feet. Now we subtract: 300-180=120 cubic feet, so 120 cubic feet of soil was removed.
