It depends on the units of your measurements in. You also need to know the weight of a bag of cement. The instructions on the bag of cement should also help.
Bags of what? Grass seeds? Cement? Sugar?
To make 1 cubic meter of concrete, you typically need about 350 kg of cement and 700 kg of ballast (aggregates). Given that each bag of cement weighs 25 kg, you would need 14 bags of cement. For ballast, with each bag also weighing 25 kg, you would require approximately 28 bags of ballast.
How much does a bag of cement weight? Know that and you have a very simple formula: y = 4000/x where x is how much a bag weights and y is your answer.
It will say on the bag how much area it will seed. You need to know the area of the ground you are seeding.
9.72 Cubic Yards of Concrete is required, if you are going to order by cement truck. 874.8 bags of 40# (40 lbs) bags, or 583.2 bags of 60# 437.4 bags of 80#
Bags of what? Grass seeds? Cement? Sugar?
How many bags of cement am I going to need, for a screed floor finish in 5.4m³?
To find out how many 94-pound bags of Portland cement are needed for a yard of sand, you typically use a 1:2:3 mix ratio (cement, sand, gravel) for concrete. Since a yard of sand weighs about 1,600 pounds, you'll need approximately 533 pounds of cement for that mix. Given that each bag of Portland cement weighs 94 pounds, you would need about 6 bags (533 ÷ 94 ≈ 5.67). Therefore, you would need 6 bags of Portland cement for a yard of sand.
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.

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
There are 27 cubic feet in a cubic yard, and a 60-pound bag of cement typically yields about 0.45 cubic feet when mixed. To fill one cubic yard, you would need approximately 60 bags of 60-pound cement.
It depends on the usage of the concrete. For footings, you would need 5 bags of cement. For sidewalks, etc. you would need 6 bags. Generally, if you know the usage it's for, you can contact a local ready-mix plant and they can tell you exactly.
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.
6 x 4.32 = 25.92 so you will need 26 bags. You might want to get up to 10 % extra for waste.
To make 1 cubic meter of concrete, you typically need about 350 kg of cement and 700 kg of ballast (aggregates). Given that each bag of cement weighs 25 kg, you would need 14 bags of cement. For ballast, with each bag also weighing 25 kg, you would require approximately 28 bags of ballast.
1 50kg bag fill about 2 cubic f. so for 102cu.f. you'll need 51 bags
