84" x 84" x 5" = 35,280 cubic inches = 20.41667 cubic feet = 0.756 cubic yard (rounded)
I have no idea how much weight that is, but the man at the lawn and garden store,
home improvement mega-store, or landscaping contractor will know immediately.
8*5*1/2 = 20 cubic feet.
8 ft * 10 ft * 0.5 ft = 40 cubic feet
lots and lots
To calculate the amount of sand needed to fill a sandbox measuring 4 feet long, 4 feet wide, and 2.5 feet deep, first find the volume by multiplying the dimensions: 4 ft x 4 ft x 2.5 ft = 40 cubic feet. Therefore, you will need 40 cubic feet of sand to fill the sandbox. If you're purchasing sand, check the bag specifications to determine how many bags you'll need based on their volume.
Assuming the box was empty to begin with there will be 8 inches of sand now.

6.2 cubic feet
just about 32 cubic feet of sand
(60" x 100" x 6") = 36,000 cubic inches
12.5 cubic feet
ABOUT 43 bags. Dry sand weighs ABOUT 100 lbs per cubic foot- and you need 21.3 cubic feet.
It depends on the density of the sand. Certainly, you are talking about 56 cubic feet, but you will need to know the bulk density of sand to figure out how much that weighs.
It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
