I'm having trouble visualising a 16 x 4 pool as being round. It sounds rectangular to me. Something round can only have one dimension, the diameter, and the height which you give as 2 inches. Please resubmit.
Assuming your pool is 16 feet in Diameter. The area would be 201 sq ft. The volume at 2" deep is 33.5 cu ft. Compacted sand is about 115 lb per cu ft in density. Thus you need about 3900 lb of sand or say 2 tons.
If the pot is round and 14 inches across, theneach 1 inch deep is 2/3 gallon (within 0.04%).
17 inches
Main lines are generally found at least 24 inches deep, while service lines are generally found at least 18 inches deep. However this may change due to regrading of the surface after the original burial of the lines.
62/3 cubic yards for every 1-foot deep. 5 cubic yards for every 9-inches deep. 31/3 cubic yards for every 6-inches deep. 5/9 cubic yard for every 1-inch deep.
Forget it. Saturn is in a deep pit of gravity.
The volume of an area 24 feet round and 45 inches deep is: 1,700 cubic feet.
A hole 40 inches deep by 12 inches wide has a volume of: 2.62 cubic feet.
48 what deep? Inches, miles, etc.
12 ft round by 30 inches deep
489.76 gallons of water.
Not to deep so your horse doesnt fall through so round about 2 inches deep
About 3,758 gallons.
1.963 cubic feet
About 4,650 gallons.
20000
About a ton.
It depends on how deep it is. If it is 6 inches deep, you will need 77 yards.
