For 1:2:4 Mix Ratio

1m³ of wet concrete assuming that total dry volume of material required = 1.54m³

1 + 2 + 4 = 7

cement: 1/7 x 1.54 = 0.22m³

fine agg: 2/7 x 1.54 = 0.44m³

coarse agg: 4/7 x 1.54 = 0.88m³

For batch mix of 240 moulds/pieces of 0.0034m³ cube (ie 0.15 x 0.15 x 0.15 = 0.0034m³)

Total volume for 240 moulds/pieces = 240 x 0.0034 = 0.816m³

Total volume of cement in the 240 moulds/pieces = 0.22 x0.816 = 0.17951999999999999m³

Total volume of fine agg in the 240 moulds/pieces = 0.44 x0.816 = 0.35903999999999997m³

Total volume of coarse agg in the 240 moulds/pieces = 0.88 x0.816= 0.7180799999999999m³
