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.

It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.
By the yard ... 4" thick and an area 3' by 3' square.
we can weight one sheet and calculate the unit weight we can weight one sheet and calculate the unit weight
Depends on how thick the concrete pad is. At 4 inches thick and allowing for a little waste and imprecise measurements, about 350 square feet. You can check out more options with the concrete calculator below.

The weight of a square meter of concrete depends on its density, which typically ranges from 2,300 to 2,500 kilograms per cubic meter. Therefore, a square meter of concrete that is 10 centimeters thick would weigh between 230 to 250 kilograms.
The cost of a square meter of concrete can vary depending on factors such as the type of concrete mix, local market conditions, and any additional labor or delivery costs. On average, the price can range from $75 to $150 per square meter. It is recommended to obtain quotes from local suppliers for an accurate estimate.
This question can not be answered because square feet are a measure of area and a cubic meter is a measure of volume.
The weight of 10mm thick glass per square meter depends on the specific type of glass and its density. On average, the weight of 10mm thick glass can range from 25-30 kg per square meter. It is always best to consult the manufacturer's specifications for the exact weight.
The weight of 1 square meter of 5mm thick glass can vary depending on the type of glass. On average, 5mm float glass weighs approximately 10.5 kg per square meter. However, the weight may differ for other types of glass such as tempered or laminated glass.
The weight of mild steel can vary slightly depending on the exact composition, but as a general rule of thumb, the weight of a 2mm thick hot rolled commercial quality mild steel sheet is approximately 15.7 kilograms per square meter.
100 mmm = 0.100 meter 28 x .1 = 2.8 cubic meters
It depends on how thick you want the concrete.
The weight of 1 square meter of 4mm thick glass is approximately 10.5 kilograms.
