I am building a labyrinth in my backyard.?

Question

the area is 18' x 14' and i need to estimate amount of material to use in border pathway. i am using rocks to form a maze type labyrinth in the shape of a half circle, what is the formula to use to get enough for the job?

Answer 1

This will entirely depend on the design you use for the maze, how high you build the partitions, how wide the paths are, etc.

As a rough estimate, you could do 3 concentric semicircles 3 feet apart, so you would need 54 feet of divider. However, you may want your paths narrower than that.
