50 lb bag covers a .5 cubic foot
To convert the weight of the sand into a volume and find out how much you need you would need to know the density of the sand as the more dense it is the less sand there will be in a 50lb bag and the more bags you would then need to fill the yard
depends on what you mean by 5x5, would that be feet or yards If feet then 3.75 bags If yards then 33.75 A 50lb bag of sand is 0,5 cubic feet
sand (silicon dioxide) has a specific gravity of about 2.7 8x12x2/12 = 16 cubic feet 16 x 62.4 x 2.7 = 2695.68 pounds of sand 2695.68 / 50 = 53.9136 or 54 bags of sand
You need10.8/(the number of cubic feet of sand in each bag) bags.
dry sand = .5 or 1/2 cubic feet
it is 100 bags of sand/ballast
The answer will depend on how big (or small) the bags of sand are!
I'll use the density of dry, packed sand, which is 100 lbs per cubic foot, 50/100 is 2 50 lb bags of sand
