You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
10.94 bags
Mainly it is because of water cement ratio(w/c ratio) Handling of cube Treatment of cube Curing
1:2:4
To make 1 cubic meter of concrete, you typically need about 1.5 cubic meters of sand and gravel combined. The general ratio for mixing concrete is 1 part cement, 2 parts sand, and 3 parts gravel. Therefore, for 1 cubic meter of concrete, you would need 0.5 cubic meters of cement, 0.75 cubic meters of sand, and 0.75 cubic meters of gravel.
1) weight of cement in one cube divided by density of cement = volume of cement in a cube: 2) Similarly volume of fine & Coarse aggregate can be calculated 3) Adding all one will get volume of solids in a Cube-Vs: 4) Subtracting Vs from volume of cube Vc one would get volume of voids Vv 5) taking ratio of Vv to Vs one would get void ratio

For 1 meter cube of brick work, you would need approximately 13 bags of cement.
