I could just tell you, but it would be better if you knew how to figure it out. So I'll do both.
A cubic yard is equal to 27 cubic feet ( 3 x 3 x 3 feet ).
or 46,656 cubic inches.
Your garden is 104 x 144 x 12 inches or 8-2/3 x 12 x 1 feet.
( Let's stick with feet and eliminate one conversion! )
8-2/3 x 12 x 1 = 104 cubic feet.
Taking your measurement and dividing it by the number of cubic feet in a cubic yard gives us -
104 / 27 = 3.85 cubic yards
Call it 4 cubic yards to fill any little imperfections and you're good to go.
12 feet = 4 yards
8 inches = .2222 yards (8inches/36inches)
4 yards x 4 yards x 0.22222 yards = 3.5555 yards
You already have a square yard of topsoil, so how does 20 inches of depth get you the volume of topsoil? There are 36 inches in a yard, and you have 20 inches of topsoil depth that's 20/36ths of a yard of topsoil depth. That's 0.555... or about 0.56 yards. The volume of topsoil is 1 yard by 1 yard by 0.56 yards, or about 0.56 cubic yards of topsoil.
Slightly less than 26 cu. yards.
15.833... [cubic] yards.
Almost exactly 2.00 cubic yards for every inch of topsoil depth.
if that is 3 ft deep it would require 96 yards... IF it is 3 inches deep it would require 24 cubic yards
77/9 cubic yards for every inch of depth.
8 yards = 288 inches, since there are 36 inches in a yard.
14.8 yards
82 yards=2,952 inches
135 inches = 3.75 yards
Insufficient information.You need to know the depth of topsoil you want to cover those 7550 sq ft.By "yards" I assume you mean cubic yards -- a volume measurement.
77 inches is 2.1388888889 yards. 77 inches is 2.1388888889 yards.
