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.
It will cover about 8 sq.feet if you spread it one inch thick.
The weight of 1 cubic meter of granite will depend on its specific density, but on average, it ranges from 2,600 to 2,700 kg/m3. For a slab of granite that is 2 cm thick, the weight can be calculated by multiplying the density by the volume (area x thickness). The thickness of 2 cm will only affect the total weight slightly compared to a full cubic meter slab.
The density of a thick rubber band can vary depending on the specific material and composition of the rubber. However, most rubber bands have a density around 1.0 to 1.2 grams per cubic centimeter.
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
For a 1000 sqft slab with a thickness of 4 inches, you would need approximately 33 cubic meters of concrete. This calculation is based on the assumption that 1 cubic yard of concrete covers 81 square feet at 4 inches 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.
To find out how many yards of concrete you need for your 450 sq ft patio, you would first need to determine the thickness of the concrete you plan to pour. Let's assume a standard 4-inch thickness. One cubic yard of concrete would cover 81 square feet at a 4-inch depth. So for a 450 sq ft patio at 4 inches thick, you would need approximately 5.56 cubic yards of concrete.
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.
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.
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.
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.
