Q14. A contractor is excavating the below trench. The contractor is supposed to dig the
trench 5ft deep and 3ft wide. The soil was tested to have an approximately swell factor of
112% and a shrinkage factor of 14%. The contractor is placing a 10" water pipe in the trench
and then backfilling with the soil that was removed. The dimensions are on center line.
Does the contractor have enough soil to backfill the trench, or will he /she have to need
more? If more soil are needed, how much does the contractor need to bring in. Answer in
LCY.

Please explain the answer.
A circular duct measures 51⁄2 inches in radius and is 30 inches long. It has a5⁄8-inch lap seam and a 7⁄8-inch overlap.
