You say 12'x12 `—> that ' is the sign for feet. so if the patio is 12 feet by 12 feet then it is 144 square feet. You don't say what measurement the "4 thick" is, but I presume it is inches. 4 inches is 1/3 of a foot, so divide the square footage by 3 and that will give you the cubic footage - if the patio is 12 feet by 12 feet and 4 inches thick then the cubic footage is 48.
144
That depends how thick you spread it! It would make more sense to ask about the weight (or mass) per cubic yard, cubic foot, etc.
It will cover about 8 sq.feet if you spread it one inch thick.
250mm x 224mm x 50mm = 2,800,000 cubic mm
I looked up the density of aluminum, and found 167 pounds per cubic foot.I would have preferred it per cubic inch, as that would have meant less work,but I guess I can convert it.1 cubic foot = 1,728 cubic inches.Density of aluminum = 167/1728 pound per cubic inch.Volume of the sheet = 20 x 20 x 0.25 = 100 cubic inches.Weight = 167 x 100/1,728 = 9.664 pounds
It is 3.8 to 5.1 centimeters thick
That depends on how thick you want it. Multiply 18ft * 18ft * thickness (in units of feet). That will give you your volume in cubic feet. To convert it to cubic yards divide your answer by 27.
16 x 16. Actually if you do the math, you could do a 18 x 18, but you never get 4 yards and you rarely get a form that is a perfect .33 feet.
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.
6 inches = 1/6 yardVolume = (length) x (width) x (thickness) = (9 x 6.5 x 1/6) = 9.75 cubic yards
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete
It all depends on the thickness, which you left out of your question.At 4" thick, it would be about 4 1/2 cubic yards.At 6" thick, it would be about 6 3/4 cubic yards.At 8" thick, it would be almost 9 cubic yards.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
I think you mean 6 inches thick, not 6 feet thick. You would need 200 cubic feet, or 7.4 cubic yards.
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.
That depends on how thick you are pouring the slab (or patio or whatever). Say for example you're pouring it 6 inches deep, which is 1/6 yard. You could get 6 square yards, which (times 9) is 54 square feet.
At 4" thick you would need at least 7.04 cubic yards. At 6" thick you'll need at least 10.56 cubic yards. If the slab is 2" thick, you'll need 3.52cubic yards.
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.
