depend on the stone used for the gravel.
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
10 lbs per sf.
The atmospheric pressure is roughly 1 bar, or 100,000 pascal. That means 100,000 newton per square meter (equivalent to the mass of about 10 tons). Actually, that's the approximate pressure at sea level; the pressure (force or weight per square meter) varies a lot depending on the altitude.

It depends on the glass type, but for general purposes it is about 19.8 kilograms per square meter
6mm glass weighs 16 kg/m2 or 3.27 lbs per square foot
6mm glass weighs 1.5Og/cm2. therefore 15Kg / m2
25
25 kg/m2 is a density of a toughened glass with 10 mm thick. If you want convert that measure into kN, then multiply by the factor "g" that is gravity (9.81 m/s2) and you get 25 x 9.81 = 245.25 kN/m2.

roughly 9 kg
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?)
30kg/m2
