Thisquestion needs clarifying. The question should be 'how much does a CUBIC metre of concrete weigh'. A square metre of concrete would have to have a thickness to make volume.
That would depend how thick the concrete is. If you mean a cubic foot, it's about 15 lbs, though concretes do vary.
I can't be exact as concretes vary. It's about 540 lbs.
9x8x1'=72cubft
72/27=2.66cuyds
2.66*1.5 (1cubyrd weighs approx 300lbs) = 3.99 tons
Concrete is sold in cubic (volume) measurements not square (area) measurements.
That would depend on what material you have a square meter of paper is going to be lighter than a square meter of rocks. Square meters don't just convert to tons you have to have a square meter of something
4,046.85645 square meters.
1472 pounds
8.325 a sq meter.
1.3 ton
Concrete is sold in cubic (volume) measurements not square (area) measurements.
The answer depends on the material and quality of the carpet.
You cannot weigh an area. Just as you cannot weigh a distance. (How much does one centimeter weigh?)
Approximately 2.0 tonnes/m3.
compare 0.76 cubic meter to kilogram
560 kilograms
depend on the stone used for the gravel.
how much does a gallon of concrete weigh
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
There are too many variables that are not quantified in the question to answer this. What kind of concrete? (There are different kinds.) Is the concrete reinforced? How is the square of concrete supported? What is the nature of the load and how is it distributed on the slab? We could go on.
You cannot weigh an area, but you can weigh a volume... so, one cubic meter of stainless steel weighs 7480 - 8000 kg. See related link for the source.
