What is the cubic yards or square footage for every bottle

Each bottle of Cement Color will color up to two 80 lb. bags of QUIKRETE® Concrete. An 80 lb. bag of QUIKRETE® Concrete Mix yields approximately 0.6 cubic feet of concrete. For every cubic yard it would take 45 bags (of 80 lb each) QUIKRETE® Concrete Mix, which would require approximately 22.5 bottles of the QUIKRETE® Liquid Cement Color (No. 1317). Yields will vary based upon waste, uneven subgrade, spillage, etc. Each bottle would need to be shaken well and thoroughly mixed with the clean water prior to mixing in the concrete.
