Answer Posted / rajesh satapathy

if you know the mix proportion, half of ur problem is solved.
now calculate the weight of sand per bag of cement.i.e 82 kg.
now calculate the volume of box for sand= mass/density.
tak bulk density of sand approx-1400kg/cum.
now ur free to deside the dimension once u got the volume. u can mak it two boxes for easy handling.
