How many 80lb bags of concrete for 8x10 slab 3in thick?
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).
How many 80lbs bags do you need for a 16x14x2 slab?
A two-inch slab is fundamentally unsound because it's not thick enough. So...go with at least a three inch slab. For a 16-foot x 14-foot x 3-inch slab: The slab is 224 square feet. Divide by four and you get 56 cubic feet. Add 10 percent (because the bottom isn't flat) and you come up with 61.6 cubic feet. There are 0.6 cubic feet in an 80-pound bag, so you need 103 bags. Do not do it this way. It will cost you more money and the pour will be weak and look terrible. You need 2-1/2 yards of concrete from a concrete company. If you make the slab 4 inches thick, you will need 3 yards and that's better because concrete companies don't like to deal in half-yard increments.
How many 80 lb bag cement to make 10x12 slab 3in thick?
To calculate the number of 80 lb bags of cement needed for a 10x12 foot slab that is 3 inches thick, first determine the volume of the slab in cubic feet: 10 ft x 12 ft x (3/12) ft = 30 cubic feet. One 80 lb bag of cement typically yields about 0.6 cubic feet of concrete. Therefore, you would need approximately 30 / 0.6 = 50 bags of 80 lb cement to complete the slab.
How much concrete to poor a 2 x 7' x 12' slab?
Use the metric system, it's more practical. Just do width * height * lenght of the area. This will get you something in CM^3. Then just do / 100^3 and you have M^3, the bags of concrete you buy will say how much M^3 you can pour with it.
How many 80 POUND bags of concrete are needed to cover 7 cubic feet?
10 bags will give you 6'2/3", seven bags will give you 11 bags will give you 7'1/3". Each bag is 2/3 cu feet.
How many square feet does one pound of concrete cover?
How deep? Are you talking about dry mix weight or finished weight? Concrete weighs 150 pounds per cubic foot. So if you have a 6" slab, that's 150# for 2 square feet. For a 4" slab, the same amount will cover 3 square feet. For a 3" slab, 4 square feet. Concrete mix is commonly sold in 80 pound bags. The finished weight is the mix plus the water that gets chemically bound to it. There's a guide on the bag telling how many bags you need for a given area and thickness.

How many yard of concrete is in a slab for 3 ' x 10' x 4?
To calculate the volume of a concrete slab, multiply its dimensions: length, width, and depth. For a slab measuring 3 feet by 10 feet by 4 inches, first convert the depth to feet (4 inches = 1/3 feet). The volume is then 3 ft × 10 ft × (1/3 ft) = 10 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 10 by 27, resulting in approximately 0.37 cubic yards of concrete needed for the slab.
