how many bags of cement for a pad 4x7x4 inches thick
To determine how many 80 lb bags of cement are needed for a 5x7 area that is 4 inches thick, first calculate the volume in cubic feet. The volume is 5 ft × 7 ft × (4/12) ft = 11.67 cubic feet. An 80 lb bag of cement typically covers about 0.6 cubic feet, so you would need approximately 20 bags of cement (11.67 ÷ 0.6 ≈ 19.45). Therefore, you would need 20 bags to complete the project.
You will need 5.5 40kg bags for this floor. This allows for a typical waste factor of 5%
To calculate the number of 80 lb bags of cement needed for a 10x12 foot slab that is 3 inches thick, first determine the volume of the slab in cubic feet: 10 ft x 12 ft x (3/12) ft = 30 cubic feet. One 80 lb bag of cement typically yields about 0.6 cubic feet of concrete. Therefore, you would need approximately 30 / 0.6 = 50 bags of 80 lb cement to complete the slab.
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.

Well, darling, if you want a concrete slab that's 5 inches thick, you'll need about 0.012 cubic meters of cement and 0.06 cubic meters of sand per square meter. Just make sure you mix it well and pour it like a boss. Good luck with your project, sugar!
The answer will depend on the size of the cement bags! The answer will depend on the size of the cement bags! The answer will depend on the size of the cement bags! The answer will depend on the size of the cement bags!
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.
7 bags cement

some bags are not thick enough,although there are lots of bags there are strong and thick
4.4 bags
