How many cubic yards in an 80 lb bag of cement?

AnswerThere is 2/3 cu. ft. per 80 lb. bag of pre-mixed concrete. Answer

It takes 133 pounds of quikrete to make 1 cubic foot, so...

- there is 0.6 cubic feet (80/133) in one 80 pound bag, and it takes one and two-thirds 80 pound bags of quikrete to make 1 cubic ft (133/80 = 1.66).

- there is 0.45 cubic feet (60/133) in one 60 pound bag, and it takes about two and one-quarter 60 pound bags of quikrete to make 1 cubic ft (133/60 = 2.22).

- there is 0.3 cubic feet (40/133) in one 40 pound bag, and it takes three and one-third 40 pound bags of quikrete to make 1 cubic ft (133/40 = 3.33).

Multiply by 27 to get cubic yards (so it would take 45 eighty pound bags to make a cubic yard).
