How much sand do I need for the planned sandbox?
How much fun your kids have playing in the new sandbox depends not least on the amount of sand that's in the box. There should be enough sand to play with and build.
How to calculate the required amount of sand:
To calculate how much sand you need for your sandbox, there is a simple formula. Multiply the length by the width and height of the planned sandbox (each in centimeters). On the Internet you will find a special calculator for it. Here is an example calculation for a square sandbox with 1.20 m edge length and 50 cm height:
120 × 120 × 50 = 720,000
Since the sandbox should only be half filled with sand, you calculate 60 percent of the result. So your kids have enough sand to play with, but not so much that they're constantly being shoveled over the edge.
720,000 x 60: 100 = 432,000
With an assumed density of sand of 1.3 g / cm³, multiply the number by 1.3 and divide it by 1000. The result is the required amount of sand in kilograms.
432,000 x 1.3: 1,000 = 561.6 kg of sand
Which sand should I buy?
Buy only declared game sand. This is examined for pollutants and germs. In addition, the grain may only have a predetermined size. To fine sand could be inhaled by children playing, on coarse sand on the other hand irritate the still quite sensitive skin of children.
Where can I get game sand?
Spieland you get in the hardware store as well as in the well-stocked garden center and of course on the Internet. Mostly it is packed in 25 kg sacks. When ordering, pay attention to the shipping costs. Transport the sand in your car, then put in a tarpaulin for safety, which will make it easier for you to clean later if a bag is broken.
