square feet to cubic yards
How do I determine how many cubic yards are in 800 square feet.

#2




Re: square feet to cubic yards
I think it would be square feet in one cubic yard divided into 800.
27 = square feet in one cubic yard 800/27=29.630 Hope this helped you.

9 square feet to one cubic yard.
800/9 = 88.89

Re: square feet to cubic yards
It depends on the thickness.
I assume this is something like sand or gravel or soil. Just need to know how thick you plan on spreading it.

Concrete  3825 sq ft / 4 inches thich

Re: square feet to cubic yards
3825 square foot * (4 inches / 12) foot = 1275 cubic foot
1275 cubic foot = 47.222 cubic yard

Re: square feet to cubic yards
There are 81 square feet to a cubic yard, providing the depth is one foot.
The typical formula for conversion is (Length in Feet X Width in Feet X Depth in Feet) / 27 = CY. Example: 100' (L) X 200' (W) X 6" (D) = 20000 X .5 = 10000 SF / 27 = 370.37 CY

Re: square feet to cubic yards
You need a thickness measurement as well ie square is 2 measurements, cube is 3
since 1 cubic yard = 27 cubic feet ( 3'x3'x3') Let's say you are using sand 12" thick over 800 square feet, You'll need a common denominator so 12" = 1 foot thick 1X800 = 800 cubic feet/ 27 cubic feet(feet in a cubic yard) = 29.62 cubic yards at 1 foot thick if it's 1" thick.. it's 29.62x1/12 (since 1 " is 1/12th of a foot) = 2.47 cu yds if it's 4" thick.. it's29.62 x 4/12 (4/12=.333) so it's 29.62 x .333 = 9.86 cu yds Now.. if you're using topsoil... for under sod or for a garden factor in compression. add about 15%
