How many 20 kg bags of cement will you need to mix with 13 cubic meters of sand if you want to mix at a ratio of 8 sand to 1 cement?

Answer 1

If a 20kg bag of cement=0.1m3 with 100 lots o 0.01 to 1m3 then you will need 12.5 bags per m3. So you need approx 11.5m3 of sand and 144 bags of cement (144 x 0.01 = 1.44m3) to give you a total of 12.94m3
