can you help a damsel in distress trying to work out a 4:1 ratio of sand and cement in 25 kg bags for a 30 sq m patio probably 5 cm deep I guess?Have looked at the 3:1,6;1 and 10:1 calculator but other books,advice recommend that 4;1 is a good working ratio.Help! ???

1.5 cubic m of sand
30 bags cement

personally you don't need that much cement though, you could do it leaner
