That is 53x1 x 8/12 = 35.33 cubic feet. That is 1.31 yards and weighs 5300 pounds
Just find the volume of the sidewalk. First get everything into Feet. Divide 4 by 12 and get 1/3' which is about .3333'. Now just multiply 36*5*.3333=60 ft.³
Where are 12 inch concrete blocks applied?

Well, you make a sidewalk from concrete, not just cement. Concrete consists of cement, sand, gravel and water. You will need 5.5 cubic feet of concrete. A standard sidewalk grade of concrete would be 1 part cement, 2 parts sand, 3 parts gravel- so the sidewalk needs 0.91 cu ft of cement- about 87 pounds worth- plus sand and gravel. If you want to buy the premixed bags of concrete (like Sacrete), you will need about 17 of the 40 pounds bags. And you did not ask, but 3 inches is kind of skinny- I would go for at least a 4 inch thick sidewalk.

The sun emits all of the electromagnetic spectrum. The part that heats the sidewalk is the infrared region which is invisible and has a long wavelength. Dark objects absorb much more heat than lighter objects so that asphalt pavement will get much hotter than concrete.

That would depend on the amount of sidewalk. ie. width x length. also the depth 4" or 6" the mix of the sidewalk, usually a city/county specified mix. and the contractors and suppliers rates. Best bet is to get several bids from local licensed contractors.
You need the dimensions of the column to calculate the volume. The formula would need to include the three dimensions in some form.
