what is the number of cement bags (50 KG) required for
concreting 1000 Square Feet Slab . Thickness of slab 4 inch.

Answer Posted / pradeep

1000 sq ft * (4/12) = 333.33 ft^3
now,
333.33 ft^3 * 0.02832 = 9.44 m^3
take 1:2:4 ratio per m^3 cement 310 kg
now,
310 * 9.44 = 2926 kg
2926 * (5/100) wastage =3072 kgs
3072/50 = 61.44 take 61 bags
