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.
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.
A4 paper 210mm by 297mm in size, which equals 62370 square millimeters. 150 GSM is 150 grams per square meter. 1 meter is 1000 millimeters, so 1 square meter is 1000x1000=1000000 square millimeters. You can fit 1000000/62370 A4 pages into 1sq meter, which is 16.0333493666827 pages. 150grams divided by 16.0333493666827 is 9.3555. So - a 150GSM page of A4 paper weighs 9.3555 grams.
we can weight one sheet and calculate the unit weight we can weight one sheet and calculate the unit weight
It depends on the size. If each sheet is 1/500 of a square meter large then the weight would be 130 grams. 130 gsm means 130 g/square meter. Thus, to find the weight, find the area of each sheet of paper in square meters, multiply it by the total number of pages (finding total square meterage) and then multiply it by 130.
An A1 sheet of 80gsm paper weighs approximately 80 grams. This weight is based on the standard measurement for paper weight, which refers to the weight of one square meter of paper.

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?)
It depends on the glass type, but for general purposes it is about 19.8 kilograms per square meter

On average, 3mm toughened glass weighs approximately 7.5 kg per square meter.
