It depends on the weight of the bag.

To calculate the volume of any bag we need to know the density. In freshly packed bags the standard density is 94 lbs/ft3 (1505 kg/m3).

Example: to know the volume of a 50kg cement bag we divide the bag weight by the density, i.e.:

50 kg ÷ 1505 kg/m3 = 0.0332 m3

In practise, sand, cement and gravel are sold by weight, yet they must be mixed by volume. the black rubber buckets used in the building trade hold one 25kg bag of cement. a standard builders wheelbarrows volume is 70Lts so holds 4 of these buckets. The standard shovel here in Ireland is the long handled dovetail and 4 heaped shovels fills a bucket as near as need be.

How much concrete does a 80lb bag yield?

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.


Why does an 80 pound bag of concrete only weigh around 67 pounds.?

P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^


How big is a bag of concrete?

Usually concrete mix comes in 40, 60 or 80 pound bags.


How many 80 pound bags of concrete mix fills a 3 yard mixer?

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.


How many bags of cement it takes to build a concrete wall three feet high and 50 feet long?

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.

How many 80 lb bag of concrete 50 lb bag of sand and 50 lb bag of gravel does it take one yard of concrete mix?

This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.

How many cubic yards in an 80 lb bag of cement?

AnswerThere is 2/3 cu. ft. per 80 lb. bag of pre-mixed concrete. AnswerIt takes 133 pounds of quikrete to make 1 cubic foot, so...- there is 0.6 cubic feet (80/133) in one 80 pound bag, and it takes one and two-thirds 80 pound bags of quikrete to make 1 cubic ft (133/80 = 1.66).- there is 0.45 cubic feet (60/133) in one 60 pound bag, and it takes about two and one-quarter 60 pound bags of quikrete to make 1 cubic ft (133/60 = 2.22).- there is 0.3 cubic feet (40/133) in one 40 pound bag, and it takes three and one-third 40 pound bags of quikrete to make 1 cubic ft (133/40 = 3.33).Multiply by 27 to get cubic yards (so it would take 45 eighty pound bags to make a cubic yard).To further help calculate how much you need for your project, you can visit the Related Link.


How many cubic feet in a bag of cement?

to calculate the volume of any bag we need to know the density. In freshly packed bags the standard density is 1440 kg/m3.Example: to know the volume of a 50kg cement bag we divide the bag weight by the density, i.e.:50 kg ÷ 1440 kg/m3 = 0.0347 m350kg = 0.0347 m3,50kg = 1.23 CFT======================================In the USA, a bag of cement usually weighs 94 pounds and has a volume of 1 cubic foot.
