Correction in Question we made:
What is the quantity of cement, sand, and gravel to be used
in M20 grade of concrete for 1000 x 1000 x 1000 mm.
(for cement please mention in kilos, and for sand and
gravel please mention it in CFT)
1000mmx1000mmx1000mm =1 mx1mx1m = 1cum ok
M20 Grade =1:1 1/2:3
summation of proportion=1+1.5+3=5.5
1.54cum of dry materials of concrete will yield only 1 cum
concrete after adding water.
1cum x1.54/5.5= 0.28 cum
so cement = 0.28cum x 1440 = 403.5 kg
sand = 0.42cum x 10.47 = 4.40 cft
aggregate = 0.84cum x 10.47 = 8.80 cft
