A cubic yard of sand approximately weighs 1.3 tons, 2,600 pounds ,or (for non imperial people) 1,179.34 kilograms.
Find the weight of the gravel by subtracting the weight of the box -- 5 pounds -- from the combined weight of 110 pounds. The result is 105 pounds per cubic foot of gravel. Multiply the weight of the gravel, in this case 105 pounds, by 27 to determine cubic yards because there are 27 cubic feet in 1 cubic yard. The result is 2,835 pounds per cubic yard of gravel.
