Where are 12 inch concrete blocks applied?
2000 pounds
A square foot of concrete has no weight because a square foot has no thickness. A cubic foot of concrete would weigh 65 Kg (143 lb) If you ASSUMED that concrete driveways, paths, etc. are all the same thickness , which they are NOT, then let us say they are 4 inch thick (10cm) In that case, then 1Square Ft of Concrete would weigh one third of the figure given above. Therefore it weighs 48 lb which is the same as 22 Kg.. Density of Concrete is 34.4 gram per cubic Inch or 1.216 ounce per cubic inch. (since you seem to be wanting to use Imperial measure)
well the density of concrete can vary from 2200kg/m3-2800kg/m3 but 2400kg/m3 is the most common
Each paver is 12" x 12" or 1 square foot. So, 200 ft2 * (1 paver/ 1 ft2) = 200 pavers
You would multiply 2 times 1.33. that would give you 2.67 square feet.
128; each paver is half a square foot.
Cooper weighs 542 lbs. per square foot. So, 542 divided by 1,728 (the number of inches per square foot). One cubic inch of copper weighs 0.31 lbs., or about 5 ounces.
A 74 inch sturgeon would weigh about 126 pounds.
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
27 lbs
A 22 inch monitor would approximately weigh 5.5 kg
