What is formula for figuring concrete slab?
If the slab is 4 inches thick the formula to find cubic yards is: Lenght x Width divided by 81 For a 6 in thick slab: Lengh x Width divided by 54 Another formula is to convert all measurements to inches and then: Lengh x Width divided by 46,656 (the number of cubic inches in a cubic yard)
How square feet in one yard of concrete?
It is impossible to answer the question as asked because square feet is a measure of area and a "yard of concrete" actually refers to a cubic yard of concrete. However, if we make a couple assumptions we can answer the question I THINK you're asking which is, "How many square feet of concrete does one cubic yard of concrete yield if poured to a typical depth of 4 inches?" The inches of depth can be changed to suit the situation, but in any case giving the poured concrete a depth turns it into a volume which makes it easier to compute the area a cubic yard of concrete will cover. To begin, we need to convertt the square footage of concrete (which is an area) to a volume. Let's use 6 inches for the depth: 12" x 12" x 6" = 864in^3 or 864 cubic inches This is the number of cubic inches of concrete in one square foot of concrete poured to a depth of 6 inches. Now we put a cubic yard into the same terms, cubic inches: 36" x 36" x 36" = 46,656 in^3 or 46,656 cubic inches of concrete. Now we simply divide number of cubic inches of concrete in a yard of concrete by the number of cubic inches in a square foot of concrete poured to a depth of 6 inches: 46656 / 864 = 54 square feet. By the way, there are 27 cubic feet in a cubic yard and you may notice that 27 x 2 = 54. That's a result of the depth I chose for the poured concrete--6 inches. A square foot of concrete poured to a depth of 6 inches is equal to one half cubic foot of concrete. 27 / .5 = 54 If you want to figure square foot yield per yard when you pour the slab at 4 inches instead of 6 inches, then simply substitute 4" in the equations for 6". (36" x 36" x 36") / (12" x 12" x 4") = 81 square feet.
How many cubic inches are in one concrete block?
8 x 8 x 16 = 1,024 cubic inches.
HOW MUCH DOES A CONCRETE SLAB 24 X 24 X 2 THICK WEIGH?
To calculate the weight of a concrete slab measuring 24 x 24 x 2 inches, first determine the volume in cubic inches: 24 x 24 x 2 = 1,152 cubic inches. Since concrete typically weighs about 150 pounds per cubic foot, convert cubic inches to cubic feet (1,152 cubic inches ÷ 1,728 cubic inches per cubic foot = 0.6667 cubic feet). Finally, multiply by the weight of concrete: 0.6667 cubic feet x 150 pounds per cubic foot ≈ 100 pounds. Thus, the slab weighs approximately 100 pounds.
How much concrete to cover 3000 sq ft 6 inches thick?
To calculate the amount of concrete needed to cover 3,000 square feet at a thickness of 6 inches, first convert the thickness from inches to feet: 6 inches is 0.5 feet. Then, multiply the area by the thickness: 3,000 sq ft × 0.5 ft = 1,500 cubic feet of concrete. To convert cubic feet to cubic yards (since concrete is typically measured in cubic yards), divide by 27: 1,500 cu ft ÷ 27 = approximately 55.56 cubic yards. Therefore, you will need about 56 cubic yards of concrete.
How do you calculate concrete volume?
Length x width x thickness or depth. Starting with inches, you will come up with total cubic inches using that formula. Divide that number by 1728 to get cubic feet. divide that quotient by 27 to get cubic yards. Concrete is usually sold by cubic yard.

How many square feet will a yard of concrete cover 5 inches thick?
A cubic yard is 46,656 cubic inches. Spread to a thicknes of 5 inches, a cubic yard of concrete covers 9332.1 square inches, which is 64.8 square feet.
What formula is used to figure gallons of an object that is 48 inches long 5.625 inches wide and 3.625 inches high?
1 gallon = 231 cubic inchesVolume in cubic inches = (48 x 5.625 x 3.625) = 978.75 cubic inches(978.75 / 231) = 4.237 gallons (rounded)
Formula for cubic inches to gallons?
1 US gallon = 231 cubic inches # of gallons = (# of cubic inches) / 231
If you drill a hole twenty five feet deep and 8 inches in diameter how much concrete will it take to fill it in?
25 feet is equal to 300 inches. The radius of a hole is half its diameter, which equals 4 inches. The volume of the cylinder is given by the formula v = [Pi]r2h, so the volume of your hole is 3.14 * 16 * 300 = 15080 cubic inches. There are 1728 cubic inches to the cubic foot, so you'll need about 8.75 cubic feet of concrete, which is about a third of a yard. (More exactly, that's a cubic yard, but concrete guys just say "yard.")
If a sidewalk at your house measures 48 wide 4-inches thick and is 40-feet long how many cubic feet of concrete are in the sidewalk?
53 and 1/3 cubic feet, concrete is normally sold buy the cubic yard, this would be 1.975 cubic yards. Figure on 2.25 CU yards to be safe. You do not want to run short when pouring concrete.
