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.
To mix 1 cubic yard of concrete, you typically need about 5 to 6 bags of Portland cement, depending on the specific mix design and the desired strength of the concrete. A standard 94-pound bag of Portland cement yields roughly 0.5 cubic feet when mixed. Therefore, for 1 cubic yard (27 cubic feet), approximately 5.7 bags would be required. Always check the specific mix requirements for your project, as variations can occur.
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.
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.
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.
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.
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
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)
Bags of what? Grass seeds? Cement? Sugar?
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.
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.
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).
To determine how many bags of cement are needed for 11 yards of concrete, you first need to know the concrete mix ratio. A common mix is 1:2:3 (cement:sand:gravel). For a standard 80-pound bag of cement, it typically yields about 0.6 cubic feet of concrete. Since there are 27 cubic feet in a yard, 11 yards equals 297 cubic feet. Using a standard mix, approximately 7 to 8 bags of cement would be needed for this volume, depending on the specific mix and design requirements.
You need10.8/(the number of cubic feet of sand in each bag) bags.
