To determine the pounds of concrete needed to repave a highway, you first need to know the total area to be repaved (in square feet) and the thickness of the concrete layer (in feet). Multiply the area by the thickness to get the volume in cubic feet, then convert that to cubic yards (1 cubic yard = 27 cubic feet). Finally, multiply the volume in cubic yards by the weight of concrete (approximately 4,000 pounds per cubic yard) to find the total weight in pounds.
1.8 Cubic yards of concrete is 48.6 cubic feet. Each 80lb bag of concrete is .6 cubic feet. Therefore, you would need 81 bags. Hope that helps. GEO
1.7 cubic yards of concrete Dondeb...that is an incorrect answer...Lets do this in steps.... 1. 80 X 30 = 240 Surface feet. Divide by .50 because you want it 6 inches deep. 2. 240 divided by .50 = 120 3. 120 is the total square feet of material needed. 4. Divide by 27 as there are 27 cubic feet to a cubic yard....(120 divided by 27) 5. 4.4 cubic yards of concrete are needed, that is if you don't take into account up to 10% for loss or shortage. If this were my project I would order 5 cubic yards.
