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.
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%
To calculate the number of bags of cement needed for a slab measuring 14 feet by 11 feet and 4 inches thick, first convert the dimensions to cubic yards. The volume is approximately 4.58 cubic yards. Generally, one cubic yard of concrete requires about 5 to 6 bags of Portland cement, so you would need approximately 23 to 27 bags of cement for this slab.
To determine how many 94-pound bags of cement are needed for a 12x12 slab, first calculate the volume of the slab. A 12x12 slab that's 4 inches thick has a volume of 4 cubic feet (12 x 12 x 0.33). One 94-pound bag of cement yields about 0.6 cubic feet when mixed. Therefore, you'll need approximately 7 to 8 bags of cement to complete the slab.
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.

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.
Without knowing the area, there is no way to answer.

6
7 bags cement
4.4 bags
You'll need a minimum of 1.85 cubic yards for that size.
