To calculate the number of 80-pound bags of concrete needed for an 8x10 slab that's 3 inches thick, first determine the volume in cubic feet. The volume is 8 ft × 10 ft × (3/12) ft = 20 cubic feet. Since one 80-pound bag of concrete typically yields about 0.6 cubic feet, you'll need approximately 34 bags (20 cubic feet ÷ 0.6 cubic feet per bag).
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
50lb bags 3.7 60lb bags 3.1 80lb bags 2.3 90lb bags 2.1 These amounts are for using the redi-mix bags.
U need 1.63 80lb bags per square ft so 131bags to do 8ft by 8ft
typically one pallet, i believe theres 42 80lb bags on a pallet.
15.21 cubic yards 1369 40lb bags 913 60lb bags and only 685 of the 80lb bags.

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

Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
80lb bags of what. you need to know the density of material working with.
15.21 cubic yards 1369 40lb bags 913 60lb bags and only 685 of the 80lb bags.
There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.
You will need 3.1 cubic yards or 139 80lb bags. This assumes a waste of about 5% which is typical.
18 bags (80 pounds) of quikrete for a 4 inch thick slab.
Assuming a thickness of four inches and allowing about 5% waste, you would need 9.33 cubic yards or about 419 80lb bags.
