Assuming you wish to used bagged 'pre-mixed' concrete, the industry standard is 1/2 cubic foot yield from a 60 pound bag. Keep in mind that the true weight will vary due to such things as sand/portland/aggregate ratios. But for a simple answer, you will be close with 3240 pounds. 60 pounds per 1/2 cubic foot, = 120 pounds for each cubic foot. 27 cubic ft. per yard 120 X 27 = 3240
For Portland cement, the typical silica content is around 20-25%. To calculate the amount of silica for 42 pounds of Portland cement, you would take 20-25% of that weight. This means you would need approximately 8.4 to 10.5 pounds of silica.
You will need a minimum of 7.41 cubic yards.

There is no regular size of 'sack' and too many sizes of 'barrel'. -You need to be much more specific.
Need to know how many bags of cement I will need for a 20x10 space?
that would be about 10 pounds
500 pounds cement, 1500 pounds sand, 1600 pounds gravel. Mix with 32 gallons water
when the dentist says you need a ceiling that usually means you have a cavity and he need to fill it with cement.
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.
Topsoil weighs about 100 pounds per cubic foot 8*8*6*100 = 38,400 pounds
To determine how many ten-pound bags of ice will fill a 48-quart cooler, we first need to convert quarts to pounds. A quart of ice weighs approximately 2.2 pounds, so a 48-quart cooler can hold about 105.6 pounds of ice (48 quarts x 2.2 pounds/quart). Dividing this by the weight of a ten-pound bag of ice, you would need about 10.56 bags, which means you would need 11 bags to fill the cooler completely.
You will need 6.17 cubic yards of cement.
For Portland cement, the typical silica content is around 20-25%. To calculate the amount of silica for 42 pounds of Portland cement, you would take 20-25% of that weight. This means you would need approximately 8.4 to 10.5 pounds of silica.
1 50kg bag fill about 2 cubic f. so for 102cu.f. you'll need 51 bags
A LOT! Gunnite is make by mixing cement, sand, and water in an approximate ratio of 1 part cement to 4-6 parts sand with 1 part water using a high pressure spraying mechanism. Please note that the major component in gunnite is SAND and not cement. With this as a guideline, a 50 pound bag of cement would be mixed with at least 200 pounds of cement (approximate total mixture weight of 250 pounds). Thus,it would require approximately 8 such mixtures to equal 2000 pounds (2000 divided by 250 = 8) and since there is one bag of cement per mixture, it would require around 8 bags or 400 pounds of cement. Furthermore, one 250 pound mixture (containing one bag of cement) will cover approximately 5 square feet at a depth of 1 inch. So, to build a pool of any decent size, you will need MANY TONS of gunnite. Hope this helps ...
we need the dimensions/volume of the tank not the psi (pounds per square inch) to answer that one.
That depends on what substance you fill those cubic feet with. -- If you fill them with air, they can't hold even one pound. -- If you fill them with water, they can hold almost 219 pounds. -- If you fill them with concrete, gold, or stones, they can hold even more pounds.
