how many bags of cement for a pad 4x7x4 inches thick
You will need 5.5 40kg bags for this floor. This allows for a typical waste factor of 5%
If your talking about 4'x4'x4" thick it will take about 12 bags. Most 60# bags will do .45 cubic feet and that slab would be about 5.3 cubic feet wich equals 11.77 bags.. Mike
You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.

The answer will depend on how large and area you want the topping for. Without that information, no sensible answer is possible.
That depends on the size of your bags! My bags are 25 kg (20 l) 5 inches is 120 mm I would use 2 bags of cement and 4 bags of sand and 6 bags of gravel (well I do not buy my gravel in bags but the equivalent volume). I would mix with as little water as necessary to get a pourable consistency.

You need enough for a little less than 10 cubic feet. You can read how much coverage of cement there is per bag on the bag and determine from there. I had to use 18 bags of ready-mix on a 2 ft by 12 ft by 3,5 in thick slab,
Without knowing the area, there is no way to answer.
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.
