Answer / raghav gowda

for 1000sqft slab of 4" thk.
assume for M20 grade of 350kg cement for 1cum of concrete is
first convert the 4" thk to feet i,e 4/12= 0.333'
then, 1000x0.333= 333cft
convert 333cft to cmt i e, 333/35.28=9.438
for 9.438cmt of concrete cement required is 9.438x350=3303.3kg
then convert it in to bags
3303.3/50=66.066bags
so the cement reqired is 66.066bags.
