How much sand do you need to fill a 60X20 sand school?

To calculate the amount of sand needed to fill a 60x20 sand school, you first determine the volume. Assuming the sand school is 0.1 meters deep, the volume would be 60m x 20m x 0.1m = 120 cubic meters. The amount of sand required would be approximately 120 cubic meters, though it's advisable to order a little extra to account for settling.
