The Volume of Sand in a Circular Sandbox calculator computes the number of standard bags (0.5 ft³) and the total volume in cubic yards of sand to fill a circular sandbox based on the dimensions.
INSTRUCTIONS: Choose units and enter the following:
Volume of Sand (V): The calculator returns the number of bags of play sand and volume of sand in cubic yards. However, this can be automatically converted to compatible units via the pull-down menu.
If you've never had a sandbox before, there are few things to consider. First, sandboxes are a lot of fun and can keep your kids busy in a constructive way for long time. However, they will be covered with sand after playing. Also, unless your sandbox has a sun cover, your children will get a lot of sun. Consider generous application of Sun screen. Also, your sandbox should be porous with the ground. You don't want water to accumulate in the sand. Moist sand is fun to play with. Water saturated sand just gets you wet, and weighs a lot. Last, but not least, you will want to cover your sandbox at night. Animals, especially cats, may treat your sandbox as a latrine, and no one wants their children playing in that.
One should always use local pricing when available. Typically a bag of play sand is 1/2 a cubic foot, so twice the price will give you the local unit price for a cubic foot of play sand. However, for convenience, vCalc performs a periodic survey of commodities such as play sand. The most recent play sand survey was as follows:
