consider a nominal mix
1:4:8
cement:sand:coarse aggregate(the above nominal mix is always per volume)
now let's consider depth of roof as 1 feet.
now 1 bag of cement=1.25 cubic feet.
so let's cement volume is x,
then sand=4x and coarse aggregate=8x
now,
x+4x+8x=3200*1 cubic feet
find x,now from this value find out the no. of cement bags by dividing x by 1.25(of each bag)
