If L=100′ and W=2′, this footing will require [qty] CY of concrete. Round up to the closest number.

If L=80′ and W=2′, how many cubic yards of concrete will this footing will require? Round up to the closest number.

Top soil is usually well-graded and proper for use to backfill around structural foundations.

If L=100′ and W=2′, estimate the quantity of steel reinforcement (in tons) for the footing. Hints: assume 10% for lap and waste for the continuous reinforcement; 2″ concrete cover; #4 bars weigh 0.668 lb/ft; and one ton has 2,000 pounds.

If L=100′ and W=1.5′, estimate the quantity of steel reinforcement (in tons) for the footing. Hints: assume 10% for lap and waste for the continuous reinforcement; 2″ concrete cover; #4 bars weigh 0.668 lb/ft; and one ton has 2,000 pounds.
