The Ratio is 1:2:4 Total = 7
Ingredients of this Mixture is = 1.57
So the qty of Cement is = (1/7) x 1.57 = 0.224 cum
Volume of cement in i cum = 1440kg
therefore required cement = 1440 x 0.224 = 322.56kg
Weight of 1 cement bag is = 50 kg
so 322.56/50 = 6.45Bag
Add 5% for wastage = 6.45 x (5/100) = 6.77 bag required
Qty of Sand = (2/7) x 1.57 = 0.448 cum (1cum = 35.31 cuft)
convert cum to cuft = 0.448*35.31 = 15.18 cuft
Sand is available in unit,so 1 unit = 100 cuft
So required qty of sand is = 15.18/100 = 0.151 unit require
Qty of Aggregate = (4/7) x 1.57 = 0.89cum
Convert cum to cuft = 0.89 * 35.31 = 31.42cuft
sand & Aggregate also available in unit
so above the same as aggregate = 31.42/100 = 0.314 unit require
