How much cement for 6’ privacy fence

Hey all! I am planning to build a 6’ privacy fence in SE Wisconsin. The frost line runs deep, so I am planning to dig 4’ holes for my 4x4 fence posts. If the hole diameter is 8-10”, is 2 50lbs bags of cement enough, per post? I’ve seen some folks suggest that 2 is enough for most use cases, others say that a hole that deep should use 4+ bags. Is there an equation to provide a more accurate answer? TIA submitted by /u/uprightsleepy [link] [comments]
