I have seen that a 50 lb bag of sand covers .5 cu yd. no way... a 50 lb sack of sand is probably about 1/2 cubic foot (a cubic foot of water weighs more than 60 lbs, and sand is denser than water, even with the air spaces). You need literally yards of gravel and sand. Get it delivered in bulk, rather than buying it in bags. > > So what I'm looking for is a formula of some sort so I can figure out how > much I will need of each.
