The thickness of 30,000 pieces of paper depends on the thickness of a single sheet. A standard sheet of office paper is typically about 0.004 inches thick. To calculate the total thickness: 30,000 \times 0.004 \text{ inches} = 120 \text{ inches} So, 30,000 pieces of standard office paper would be approximately 120 inches thick.
3.05 inches is 3.05 inches thick. If you would like it converted to another unit of measure, please specify. A common note card is 3 inches wide.
Figure about 1/2 cubic foot per 60 lb bag. The basic formula is to use equal amounts of cement, sand, and gravel. There are 27 cubic yards per cubic foot. It depends upon how thick you are planning to pour the concrete. For one foot thick, you would need 9 cubic feet of concrete. For 6" thick, you would need 4 1/2 cubic feet. I'll give you the answers for 1 ft thick and for 6" thick. For 1 foot thick, you need 9 cubic feet at 1/2 cubic foot per 60 lb bag equals 18-60 lb bags. That's six 60 lb bags of concrete, plus six 60 lb bags of sand, plus 360 lbs of gravel. For 6 inches thick, divide each of these by 2 to give 3-60 lb bags of concrete, 3-60 lb bags of sand, plus 180 lbs of gravel.
I think you mean 6 inches thick, not 6 feet thick. You would need 200 cubic feet, or 7.4 cubic yards.
It is not possible to answer the question sensibly. Square feet are a measure of area, whereas weight is a property associated with volume. 10 sq feet of oak would probably weigh less than a feather if it were 1 micron thick. On the other hand, it would weigh a lot if it were 2 foot thick.
30.81 cubic yards
Concrete weighs approx 150 pounds per cubic foot. This slab would weigh approx 1188 pounds.
It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.
8.25 cubic yards of concrete
Depends on how thick it is. At 4 inches thick, you would nee about 5.5 cubic yards adjusting for safety. At 6 inches, you'd need about 8 cubic yards. You can play with different thicknesses with the linked concrete pad calculator.
151/9 cubic yards for every 12 inches thick
1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
If you made a sidewalk about 2.5' wide it would be about 13' long.
A pad that is 4 inches think covers 80ish sq ft per yard, so 8 inch would be 40ish sq ft per yard of concrete
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
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.
The weight of a square meter of concrete depends on its density, which typically ranges from 2,300 to 2,500 kilograms per cubic meter. Therefore, a square meter of concrete that is 10 centimeters thick would weigh between 230 to 250 kilograms.
