How much will an 80 lbs bag of concrete cover?
Question:If I make it about 4 inches thick.
Answers:
An 80lb bag yields 2/3 of a cubic ft per bag.
You will get 2 sq ft of coverage @ 4" thickness.
You should over estimate your bag quantity though,
You don't want to be pouring and have to go back for more.
Gary B just asked this 35 min ago. 80 lb. bag yields approx. 2 CU. FT. knowing that you can calculate the approx. sq. ft. of coverage @ 4 inches thick.

My guess since I have done it before would be about 2 to 3 ft.
If you mix gravel in that conrete you will stretch it out more.
You can mix sand too. to strecth it out, but I prefer gravel.
