At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
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.
To determine how much concrete is needed for 1 square meter (m²) of surface, you also need to specify the thickness of the concrete layer. For example, if you want a thickness of 10 centimeters (0.1 meters), you would calculate the volume as 1 m² x 0.1 m = 0.1 cubic meters. Therefore, for a 10 cm thick layer, you would need 0.1 cubic meters of concrete for 1 m².
It depends how thick you want it
You will need at least 14 cubic yards.
Well assuming the depth of concrete is going to be 1 meter you will need 846 cubic meters of concrete.
you would need 37.33 yards of concrete or 38 to be safe
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.
For a hole 36" deep X 18" diameter, you would need approx. 1/5 cu. yd. concrete.
You need the dimensions of the column to calculate the volume. The formula would need to include the three dimensions in some form.
To determine how much concrete is needed for 1 square meter (m²) of surface, you also need to specify the thickness of the concrete layer. For example, if you want a thickness of 10 centimeters (0.1 meters), you would calculate the volume as 1 m² x 0.1 m = 0.1 cubic meters. Therefore, for a 10 cm thick layer, you would need 0.1 cubic meters of concrete for 1 m².
To measure how much concrete you need for your project, calculate the volume of the area to be filled with concrete by multiplying the length, width, and height. Then, divide the total volume by the yield of the concrete mix to determine the amount needed in cubic yards or cubic meters.
1 cubic yd of a concrete mixture contains about 500 hundred lbs of cement
It depends how thick you want it
For a 4-inch depth you will need at least 7 cubic yards.
You will need at least 14 cubic yards.
