80# bags are 0.6 cubic feet and it takes 41 to make a cubic yard. In that case, 60# bags must be 0.45 cubic feet and it would take 55 to make a cubic yard.
2,000 cubic feet = 74.07 cubic yards.
4200 cubic feet
7 feet by 14 feet = 98 square feet 98 square feet by 4 feet = 392 cubic feet There are 9 square feet in a square yard, and there are 29 cubic feet in a cubic yard.... so 392 cubic feet = 14.519 cubic yards
55-ft x 12-ft x 18-ft = 11,880 cubic feet 27 cubic feet = 1 cubic yard 11,880 cubic feet = 440 cubic yards
5.28 × 103 cubic feet.
1.8 Cubic yards of concrete is 48.6 cubic feet. Each 80lb bag of concrete is .6 cubic feet. Therefore, you would need 81 bags. Hope that helps. GEO
0.6 cubic feet in one 80 lb bag. with there being 27 cubic feet in one cubic yard: 0.02 cubic yards per bag, in other words, it would take 45 - 80lb bags to yeild 1 cubic yard of concrete
Regardless of the cubic feet you are looking for, an 80lb sack of quickcrete is 2/3 cu.ft. actually .60 cu.ft. so just do the math for 100cu.ft or 10cu.ft 100 sacks= 60 cu.ft. 10 sacks= 6 cu.ft. So, for 100cu.ft you will need right at 140, 80lb sacks A lot of mixing to do!!! For a premix truck to deliver it, you will need a little less than 4cu.yards. much easier, and quite likely cheaper.
To calculate the volume of the space, multiply the dimensions: 18 ft × 18 ft × 8 ft = 2,592 cubic feet. An 80 lb bag of Quikrete typically fills about 0.6 cubic feet. Therefore, to find the number of bags needed, divide the total volume by the volume per bag: 2,592 cubic feet ÷ 0.6 cubic feet/bag = 4,320 bags. You will need approximately 4,320 bags of Quikrete to fill the space.
An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.
There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.
A standard bag of Quikrete typically weighs 80 pounds and covers about 0.6 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need approximately 45 bags of 80-pound Quikrete to make one cubic yard. If using 60-pound bags, you would need about 60 bags for the same volume.
To fill a 3'x3'x3' hole, you first need to calculate the volume, which is 3 feet x 3 feet x 3 feet = 27 cubic feet. An 80 lb bag of concrete typically yields about 0.6 cubic feet when mixed. Therefore, to fill the hole, you would need approximately 45 bags of 80 lb concrete (27 cubic feet ÷ 0.6 cubic feet per bag).
To calculate the number of 80-pound bags of concrete needed for an 8x10 slab that's 3 inches thick, first determine the volume in cubic feet. The volume is 8 ft × 10 ft × (3/12) ft = 20 cubic feet. Since one 80-pound bag of concrete typically yields about 0.6 cubic feet, you'll need approximately 34 bags (20 cubic feet ÷ 0.6 cubic feet per bag).
To calculate the number of 80-pound bags of Quikrete needed, first determine the volume of the slab in cubic feet. The volume of a slab that is 4 inches deep, 4 feet wide, and 7 feet long is 4/12 (0.33 feet) x 4 feet x 7 feet = approximately 9.33 cubic feet. Quikrete typically covers about 0.6 cubic feet per 80-pound bag, so you would need about 16 bags (9.33 cubic feet ÷ 0.6 cubic feet per bag = 15.55 bags, rounded up to 16).
To calculate the number of 80 lb bags of Quikrete needed for a 9 ft by 12 ft pad at 4 inches thick, first convert the dimensions to cubic feet. The volume is 9 ft x 12 ft x (4/12) ft = 36 cubic feet. An 80 lb bag of Quikrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 60 bags (36 cubic feet ÷ 0.6 cubic feet per bag).
1.25 cubic feet - 77 cubic feet = -75.75 cubic feet.
