It all depends on the strength of concrete needed, for a strength of 15MPA you would need 5.13 bags of 50Kg cement, for 25MPA you would need 6.59 bags, for 30MPA you would need7.7 bags. (based on Afrisam high strength cement brochure) (South Africa)
49 bags. The density of loose sand is about 90 lbs/cu. ft. There are 27 cu. ft. in a cu. yard. Therefore 27 * 90 equals a total weight of 2,430 lbs. for a cu. yard of sand. Given 50 lbs. per bag of sand, you divide 2430 by 50 and get 48.6 bags of sand. Round up to 49.
Since one bag weighs 25 kg, it takes 40 bags to make one ton

The air bags in your body cavity are called your lungs. These are the organs responsible for providing your body with the oxygen needed for survival.
Since plastic bags are not biodegradable, they slowly deteriorate into small toxic bits, contaminating water and soil. Plastic is made from chemicals that produce pollution as the plastic is manufactured. Using fewer plastic bags causes less pollution to enter the air humans and animals breathe. At times, plastic bags make their way to the ocean and marine animals eat them, thinking they are food. Some marine animals may even become entangled in the plastic bags .
7 cement bags per 1 cubic meter of concrete......
According to Blue Circle it takes 108 bags of concrete to get a cubic meter
One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over

Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
