40 / 27 = 1.481 yards x $100 = $148.00 + tax. Unfortunately you will have a hard time getting a concrete company to deliver less than 5 yards.
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.
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
To calculate the amount of concrete needed for a 12' x 36' x 4' pad, first find the volume in cubic feet by multiplying the dimensions: 12 x 36 x 4 = 1,728 cubic feet. Since concrete is typically measured in cubic yards, convert cubic feet to cubic yards by dividing by 27 (1 cubic yard = 27 cubic feet). Therefore, you would need approximately 64 cubic yards of concrete for the pad (1,728 ÷ 27 = 64).
A typical 80-pound bag of concrete mix yields about 0.6 cubic feet of concrete. A 3-yard mixer has a capacity of 81 cubic feet (3 cubic yards). To fill the mixer, you would need approximately 135 bags of 80-pound concrete mix, since 81 cubic feet divided by 0.6 cubic feet per bag equals about 135 bags.
To calculate the volume of a concrete slab that is 40 feet long, 60 feet wide, and 6 inches thick, first convert the thickness to feet (6 inches = 0.5 feet). The volume in cubic feet is 40 x 60 x 0.5 = 1,200 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard). Thus, 1,200 cubic feet is approximately 44.44 cubic yards.
25856 / 27 = 958 yards of concrete @ $75 per yard = $71,850
A cubic measure ment is required
Essentially, you need three and a third cubic yards of concrete to replace that quantity to those measurements - so if the cost of a cubic yard of concrete is 30, multiply it by 3.333 and you get 100
27 cubic feet in one yard of concrete. $90.00 divided by 27cu.yds= $3.33/cu.ft.
The weight of concrete typically averages around 150 pounds per cubic foot. Therefore, 9 cubic feet of concrete would weigh approximately 1,350 pounds (9 cubic feet x 150 pounds per cubic foot). This can vary slightly based on the specific mix of the concrete used.
An 80 pound bag of premix concrete will make .6 cubic feet of cured concrete. There are 27 cubic feet in a cubic meter, so it would take 45 80 pound bags to make one cubic meter.
When you purchase concrete you will pay by volume per cubic yard (commonly called "yard"), since a linear yard is 3 feet there are 27 cubic feet in one cubic yard. According to www.doityourself.com a yard of concrete will cost about $75.00 so a cubic foot will cost you $75/27, which would be about $2.78 per cubic foot. 1 foot of concrete is a very small volume so you will probably be charged for a minimum quantity which will be more that the cost of 1 foot. Keep the difference between line, area and volume in mind. If you need less that 10 cubic feet of concrete I would suggest you get a bag of mix from your local hardware store and follow the directions on the bag. You will need a shovel and a bucket or wheel barrel. (a 5 gallon bucket is a little over half a cubic foot) If you are thinking about mixing the concrete yourself, its a good bet to just go to home depot or lowes and write down the cost of various sizes of concrete bags. Once you have that you can enter it into a concrete cost per cubic yard tool (such as: http://righterscientifics.com/concrete-cost-per-yard.html) and figure out the total cost of your project.
To determine how many bags of concrete are needed for 1.78 cubic yards, first note that a standard bag of concrete typically contains 0.5 cubic feet. Since there are 27 cubic feet in a cubic yard, 1.78 cubic yards is equivalent to 1.78 x 27 = 48.06 cubic feet. Dividing 48.06 cubic feet by 0.5 cubic feet per bag gives approximately 96.12 bags. Therefore, you would need about 97 bags of concrete to cover 1.78 cubic yards.
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
To determine how many cubic feet of concrete are needed, you first need to know the depth of the concrete slab. For example, if the slab is 6 inches thick, you would multiply 360 square feet by the thickness in feet (6 inches = 0.5 feet) to get 180 cubic feet of concrete required.
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.
