it varies. go to your local hardware store and find out.
Concrete is sold in cubic (volume) measurements not square (area) measurements.
At a rough average density for granite of 2.7 g/cm3 the weight of a 1" thick slab of granite countertop with a front to back depth of two feet would be 28 pounds per lineal foot. Most granite countertops are close to 1-3/16" in thickness, however, raising the total weight per lineal foot to roughly 33.25 pounds. A 3/4" thick slab would weigh roughly 21 pounds per lineal foot.
1 percent of a foot is 0,3048 cm.
much water per foot will a 5 inch pipe hold
16 lbs
Concrete weighs approx 150 pounds per cubic foot. This slab would weigh approx 1188 pounds.
how much does concrete cost per square foot
m20 grade concrete per m3 load
The answer will depend on 4 inch slab of what material!
Concrete averages in weight between 90lbs per cubic foot to 140lbs per cubic foot. Knowing that its a simple equation. L x W x H = C x W. in this case 800 cubic feet. So basically the slab can weight between 72,000lbs and 112,000lbs. Length x Width x Height = Total Cubic Feet x Weight per cubic foot = Total Weight
The answer will depend on where in the world you want the job done and so the local labour rates.
if the slab is one inches thick, it should be 8.8 pound per squire foot.
whats the cost to sandblast concrete persquare foot
Short Answer: About 50 lbs per foot square by 4" slab Detailed Calculation: A number of references online give the density of concrete as 2400 Kg/m^3 which is about the density of solid limestone often used as the agregate in concrete. Given that there are exactly 2.20462262 lbs per kilogram and 39.3700787 inches per meter that works out to about 0.0867 lbs per cubic inch. Assuming you meant a 12" by 12" by 4" slab that is 576 cubic inches times .0867 which works out to 49.94 lbs per 12" x 12" x 4" slab So in the future it should be easy to remember that a square foot of concrete that is four inches thick weighs about 50 pounds. Keep in mind that different types of concrete may vary in density depending on the type of cement used, amount of water, type and size of aggregate mixed in how much sand etc. Fortunately most type of stone and sand used for concrete are pretty close in density and the excess water in the mix will evaporate. So 50 pounds per square foot 4" deep is probably a good estimate in most cases as long as there isn't a lot of steel reinforcing bar or wire embedded in the concrete. Steel is about three times as dense as stone.
