Volume of cement = (cement/cement+sand+aggregate) × Total material = (1/1+2+4) × 1.52 =0.2171 cum As we know, the density of cement is 1440 kg/cum and Weight of 1 bag cement = 50 kg. Therefore volume of 1 bag cement = 50/1440 =0.0347 cum. ∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347 = 6.25 bags.
