Question

How much sand would I need for a 15ft circle about an inch deep? Depth is for leveling purposes only.?

Answer 1

14.86 cubic feet.

Answer 2

Area of a circle is Pi R squared.

So that's 3.14(7.5 )^2 for 177 sq ft

Multiply by 1/12' depth for volume.

That's roughly 15 cu ft.

Answer 3

Sand: if gently filled into a container, the density will be small; when the same sand is compacted into the same container, it will occupy less volume and consequently carry a greater density. This is because "sand" contains a lot of air space in between individual grains; this overall density is called the bulk density, which differs significantly from the density of an individual grain of sand.

It is correct that 3.14xd^2/4 = about 14.8 cubic feet

But because of the air space I think you need less sand than that. Sand is typically sold by the pound and according to Lowe's a 50 lb. sack of sand = 0.5 cubic feet

So you would need 1480 lbs. sand!!  That doesn't quite sound right.

I would buy about half that much, spread it out and go back for more if you need it.

Answer 4

Slightly more than half of one cubic yard.

Sand will be sold by the cubic yard.
