**DrBob222**, Sunday, September 13, 2009 at 7:44pmSo 1# water

+ 5# sand

+ 2# cement

+ 6# gravel

Total = 14# for mix.

Total weight of the order = 3.5 Yd^3 x (4,000 lbs/1 yd^3) = 14,000 lbs.

water = 14,000 lbs x (1/14) = ??

sand = 14,000 lbs x (5/14) = ??

cement = 14,000 lbs x (2/14) = ??

etc.Check my thinking.
