divide the number of inches by 12. In this case: 6.7 ft.
To calculate the volume of concrete needed, use the formula for volume: length × width × depth. In this case, convert the dimensions to feet: 80 feet long, 40 feet wide, and 0.5 feet deep (6 inches). Therefore, the volume is 80 × 40 × 0.5 = 1,600 cubic feet. You would need 1,600 cubic feet of concrete for the project.
An 80-pound bag of concrete typically yields about 0.6 cubic feet of mixed concrete. To determine the square footage it can cover, you need to know the thickness of the slab you're pouring. For example, if you're pouring a 4-inch thick slab, an 80-pound bag would cover approximately 12 square feet.
To fill a 3'x3'x3' hole, you first need to calculate the volume, which is 3 feet x 3 feet x 3 feet = 27 cubic feet. An 80 lb bag of concrete typically yields about 0.6 cubic feet when mixed. Therefore, to fill the hole, you would need approximately 45 bags of 80 lb concrete (27 cubic feet ÷ 0.6 cubic feet per bag).
To determine how many 80 lb. bags of concrete mix are needed to fill an oil drum, first calculate the volume of the drum. A standard oil drum has a capacity of about 55 gallons, which is approximately 0.2 cubic meters or 7.4 cubic feet. Since an 80 lb. bag of concrete mix typically covers about 0.6 cubic feet, you would need roughly 12 to 13 bags to fill the drum completely.
To calculate the amount of concrete mix needed for an 18x20x4 pad, first determine the volume in cubic feet: 18 ft × 20 ft × 4 ft = 1,440 cubic feet. Since a standard 80 lb bag of concrete mix yields about 0.6 cubic feet, you would need approximately 2,400 bags (1,440 ÷ 0.6 = 2,400). Therefore, you'll need around 2,400 bags of 80 lb concrete mix for the project.

To calculate the formula for a 4-inch concrete slab, you typically convert the thickness from inches to feet by dividing by 12. A 4-inch slab is 4/12 = 1/3 feet thick. When calculating the volume (cubic feet) for a slab, the formula is Volume = Length × Width × Thickness. If the slab covers an area of 80 square feet, multiplying that area by the thickness (1/3 feet) gives you 80 cubic feet.

7 ft/ 80 inch so... 84 inch/80 inch 42 inch/ 40 inch 21 inch/20 inch
To calculate the area of a rectangle, you multiply the length by the width. In this case, the length is 120 feet and the width is 80 feet. So, the area would be 120 feet x 80 feet = 9600 square feet.
7/12 = 0.5833... feet (approx).
If the radius of a circle is 80 inches, then the area of the circle is 139.6263 square feet. (rounded)
There are 144 inches in a square foot so, 144 x 80 is 11520 inches in 80 square feet.

16" * 16" = 1.77777 square feet, so , 80 / 1.77777 = 45 tiles
To calculate the area in square feet, you need to multiply the two dimensions in feet. In this case, 40 feet multiplied by 80 feet equals 3200 square feet.
