Question from Jessica:

I am putting a yard pond in and I am trying to find out how many stones I would need for the perimeter.

The pond is 4ft (W) by ft (L) by 1.5ft (D)

Thank You,


Hi Jessica,

The perimeter is the distance around so think about walking around the pond. The distance is the length plus the width plus the length plus the width. The number of stones you need depends on the size of the stones.
