### How do I determine how many tons, 15 yards of top soil is ...

Let me take a density of 100 pounds per cubic foot as an example. There are 3 feet in a yard so . 100 lb/ft 3 = 100 lb/ft 3 × 3 3 /1 ft 3 /yd 3 = 2700 lb/yd 3. Since there are 2000 pounds in a ton this is 2700.2000 = 1.35 tons per cubic yard and thus 15 cubic yards weighs 1.35 × 15 = 20.25 tons.
