To make one yard of concrete from 80# bags you will need about 40-45 bags. Each bag is about .67 or 2/3 cubic foot. you will need 27 cubic feet to make 1 cubic yard. Cheaper to have a redimix truck deliver, and a lot less work.
Volume of concrete required, in square feet = 27 x 4 x 0.5 = 54 cu ft, which is 2 cubic yards, so 80 dollars/pounds/yen/ringgit or whatever.
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
1 yard = 36 inches so 80 yards = 80*36 = 2880 inches.
Wet concrete is approximately 150 pounds per cubic foot. So 80 pounds is approximately 1/50 th of a cubic yard.
80
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
41 bags. Actual 40.5
it takes 45 Bags of 80# mix to make a cubic yard
This cannot be answered without knowing the width and depth.
there are 27 cubic feet in one cubic yard.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.

0.6 cu yds 0.6 yards is incorrect. According to quikrete's website it would require 46 80# bags of concrete to cover 81 square feet at 4" thick, which is one cubic yard. Dividing 46 by 1 yard gives us approximately 0.022 yards per bag.
About 3 cubic yards (specifically 2.963 cubic yards). The volume is 80 cubic feet (4 x 5 x 4) divided by 27 cubic feet per yard (cubic yard).
At least in the Albany area it is between $80 to $100 per yard depending on the mix
