4 inches = 1/3 foot
Volume = 40-ft x 3-ft x 1/3-ft = 40 cubic feet
Based on the category I am assuming we are takling dirt or mulch. 75 yds x 27 cuft (there is 27 cuft per 1 cuyd) = 2,025 cubic feet of material - 1 foot thick would be 2,025 sqft. - 6 inches thick would be 4,050 sqft. - 3 inches thick would be 8,100 sqft.
29 inches by 15 inches = 435 square inches = 435/144 square feet = 3.02 square feet. Multiplying the number of square feet by a 3rd dimension (thickness or depth, etc.) will give an answer in cubic feet. If the 29 inches by 15 inches object is 1 inch thick, it has a volume of approximately 0.252 cubic feet (3.02/12).
There are about 8,640 cubic inches in five cubic feet.
2.78 cubic feet in 4,800 cubic inches.
If a volume is measured in cubic feet but the answer is required in cubic inches then a conversion process is needed. 1 foot = 12 inches 1 sq ft = 12 x 12 = 144 sq inches 1 cu ft = 12 x 12 x 12 = 1728 cu inches. So, to convert cubic feet to cubic inches, multiply the answer by 1728. Conversely, to convert cubic inches to cubic feet, divide the answer by 1728.
137.5 cubic feet or 5.09 cubic yards.
625 times 0.5 = 312.5 cubic feet will be needed
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
how many cubic feet in a yard of concret
It depends upon how thick you want the concrete. For example, if you want the concrete to be 6 inches thick, then you will need 200 cubic feet. There are 27 cubic feet per cubic yard; so divide the 200 cubic feet by 27 to get 7.4 cubic yards.
1 cubic yard will cover ~90 sq feet
(3.5/12) x 120 = (.2917) x 120 = 35.004 Cubic Feet Concrete is sold by the cubic yard. 35.004 cubic feet = 1.3 cubic yards
Apples and oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot. 450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards. 450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.
1 371.42857 US gallons or 5.19142188 cubic meters
4300 x .66 * = 2838 cubic feet / 27 = 105.11 cubic yards. ( *.66 = 8" )
A 10-foot round slab at 4 inches requires 1 cubic yard.
8 inches = 2/3 foot27 cubic feet = 1 cubic yardVolume of your slab = 40' x 60' x 2/3 = 1,600 cubic feet = 59.26 cubic yards. (rounded)
