We need 6.28 cubic yards (4.8 m 3) of cement, and our producer sells cement in bags weighing 60 lb (25 kg) with a density of 150 lb/cu ft (2400 kg/m 3). The total weight of concrete that we need is 942.53 lb (427.52 kg). We assume a 5% loss in wastage and spillage. So, there you go, we need 17 bags of cement. L18pVMK.
