6 x 4.32 = 25.92 so you will need 26 bags. You might want to get up to 10 % extra for waste.
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.
Cement comes in bags that weigh 94 lbs. The volume of the bag is approximately 1 cubic foot. If you want to mix concrete which is a mixture of a coarse aggregate (gravel) and a fine aggregate (sand) and something to bond the two aggregates together (cement) then firstly you need to know the strength concrete that you require. For 1 cubic yard of 3000psi (pounds per square inch) strength you will need about 6 bags cement 12 cubic feet of sand and 24 cubic feet of gravel. Rule of thumb is the ratio should be 1:2:4 (cement:sand:gravel)
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.
You will need 6.17 cubic yards of cement.
8.64 cubic yards of cement.

For M25 grade concrete, the mix proportion is typically 1:1:2 (cement:sand:aggregate). This means for 1 cubic meter of concrete, you would need 1/4 cubic meter of cement. As 1 cubic meter is equivalent to 35.32 cubic feet, and one bag of cement usually covers around 0.035 cubic meters, you would need approximately 7-8 bags of cement for 1 cubic meter of M25 grade concrete.
If a 20kg bag of cement=0.1m3 with 100 lots o 0.01 to 1m3 then you will need 12.5 bags per m3. So you need approx 11.5m3 of sand and 144 bags of cement (144 x 0.01 = 1.44m3) to give you a total of 12.94m3
1 50kg bag fill about 2 cubic f. so for 102cu.f. you'll need 51 bags
Bags of what? Grass seeds? Cement? Sugar?

You will need a minimum of 0.665 cubic meters of cement for this walkway. (if 60 lbs per bag, it is 52.1 bags. If 80 lbs per bag, it is 39 bags).
You need10.8/(the number of cubic feet of sand in each bag) bags.
The density of sand can vary, but a common value is around 1,600 kg/m^3. Assuming this density, 1 cubic meter of sand would weigh 1,600 kg. If a bag of sand typically weighs around 20 kg, you would need 80 bags of sand to fill 1 cubic meter.
You will need 6.17 cubic yards of cement.
How many bags of cement am I going to need, for a screed floor finish in 5.4m³?
