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.
A typical 80-pound bag of concrete mix yields about 0.6 cubic feet of concrete. A 3-yard mixer has a capacity of 81 cubic feet (3 cubic yards). To fill the mixer, you would need approximately 135 bags of 80-pound concrete mix, since 81 cubic feet divided by 0.6 cubic feet per bag equals about 135 bags.
I assumed here that you wanted a wall six inches thick...the answer is "more bags than you want to deal with." Specifically, at least 125 80-pound bags. The formula is: first, determine the volume of the item by multiplying the height (3 feet) by the length (50 feet) by the thickness (0.5 feet). This gives you 75 cubic feet. If the wall's thinner or thicker, of course this is going to change. Next, divide this by the number of cubic feet in a bag-- 0.30 cf per 40 pound bag 0.45 cf per 60 pound bag 0.60 cf per 80 pound bag This gives us our total bags...125 80-pound, 167 60-pound or 250 40-pound. Then add 10 percent more, just in case. This is the time I'd start thinking of other things to make from concrete, so I could order five yards of it. Five yards of premixed concrete will be cheaper than the three yards of bagged concrete you'll need, and you can't mix concrete fast enough to pour something this big.
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete
10 bags. Each 80 lb bag is 0.6 cubic feet, and your hole is 6 cubic feet.
A 60-pound bag of concrete mix typically yields about 0.45 cubic feet of concrete. To convert this to square feet, you need to know the thickness of the slab you plan to pour. For example, if you're pouring a 4-inch thick slab, the 60-pound bag would cover approximately 13.5 square feet.
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.
An 80-pound bag of sacked concrete typically yields about 0.6 cubic feet of concrete. A standard 12-inch concrete block has a volume of approximately 0.5 cubic feet. Therefore, an 80-pound bag can fill about 1 to 1.2 blocks, depending on the specific dimensions and any extra material needed for mortar or adjustments.
A typical 80-pound bag of concrete mix yields about 0.6 cubic feet of concrete. A 3-yard mixer has a capacity of 81 cubic feet (3 cubic yards). To fill the mixer, you would need approximately 135 bags of 80-pound concrete mix, since 81 cubic feet divided by 0.6 cubic feet per bag equals about 135 bags.
To make one cubic yard of concrete using Quikrete, you would need approximately 54 bags of 50-pound Quikrete. This is based on the fact that one cubic yard is equivalent to 27 cubic feet, and a 50-pound bag yields about 0.375 cubic feet of concrete. Therefore, dividing 27 cubic feet by 0.5 cubic feet per bag gives you about 54 bags.
To determine how many 80-pound bags of concrete are needed to fill a 55-gallon drum, first calculate the volume of the drum. A 55-gallon drum holds about 7.4 cubic feet (since 1 gallon is approximately 0.133 cubic feet). An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 12 to 13 bags of concrete to fill the drum.
To calculate the number of 80-pound bags of concrete needed for a 2x2 slab that is 6 inches thick, first determine the volume of the slab. The volume is 2 feet x 2 feet x 0.5 feet (6 inches) = 2 cubic feet. An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 4 bags (2 cubic feet ÷ 0.6 cubic feet per bag = about 3.33 bags, rounded up to 4).
An 80 pound bag of premix concrete will make .6 cubic feet of cured concrete. There are 27 cubic feet in a cubic meter, so it would take 45 80 pound bags to make one cubic meter.
Typically, one 50-pound bag of concrete is needed per fence post.
To fill a 30-gallon drum with concrete, you would need approximately 12 bags of 80-pound concrete. This is based on the fact that one 80-pound bag of concrete yields about 0.6 cubic feet, and a 30-gallon drum holds about 4 cubic feet. Therefore, dividing 4 cubic feet by 0.6 cubic feet per bag gives you roughly 6.67 bags, but accounting for the weight and settling, it's safer to estimate around 12 bags.
One cubic yard is equivalent to 27 cubic feet. A 60-pound bag of Quikrete typically yields about 0.45 cubic feet of concrete. Therefore, to fill one cubic yard, you would need approximately 60 bags of 60-pound Quikrete bags (27 cubic feet ÷ 0.45 cubic feet per bag = 60 bags).
