It depends on the profile and thickness of the sheets. Large profile corrugated sheets are approximately 14 kg per meter squared.
Portland cement (often referred to as OPC, from Ordinary Portland Cement) fineness 300 - 500 m2/kg
M40 grade of concrete : is recommended in extreme exposure or when very heavy loads are to be carried (like pier of a bridge etc) Under extreme exposure - reinforced M40 grade concrete should have minimum cement = 360 kg/cubm. This can vary from 300 to 360 for exposures from mild to extreme. Plain M40 grade used under mild to extreme exposure has minimum cement content from 220 to 280 kg/cubm Other considerations like admixtures (fly ahs etc) and actual mix design is the best method of arriving at minimum cement contents.

The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

The cost is: 6.7 times 5 = 33.5
20 kg @ Rs15 per kg cost Rs300 10 kg @ Rs20 per kg cost Rs200 Total: 30kg costing Rs500 So average cost per kg = Rs500/30kg = Rs16.67
