18 feet = 9 yards
12 feet = 4 yards
9 yards X 4 yards = 36 square yards
A cubic yard is 36" x 36 " x 36 "
36 " / 4" = 9 (4" sections)
Thus, 1 cubic yard has 9 square yard layers which are 4" thick
So, 1 cubic yard will cover 9 square yards 4" thick
So, 4 cubic yards will cover 36 square yards which are each 4" thick
Assuming you're talking 12 inches X 12 inches X 4 inches, then it's not much of a cubic yard - a little over .012 cubic yards (or around 1/83rd).
If you're talking 12 feet X 12 feet X 4 feet = 576 cubic feet. There are 27 cubic feet in a cubic yard so 576/27 = 21 1/3 cubic yards.
I hope that helps (and that my math's correct)
Very close to 74 cubic yards.
Here's the math . . .
All dimensions have to be in the same units, so convert 4 inches to feet. 4in/12in per ft=0.333 feet.
Find the volume in cubic feet. 120' x 50' x 0.333' = 2,000 cubic feet, more or less.
There are 27 cubic feet within each cubic yard, so divide 2000CF/27CF per CY = 74.07 CY (cubic yards).
There are approximately 1.30795 cubic yards in a cubic meter.
180 cubic feet is 6.67 cubic yards.
Divide by 27 to convert cubic feet to cubic yards= 380/27 yards
1,050 cubic feet equals 38.89 cubic yards.
There are approximately 7.65 cubic meters in 10 cubic yards.
The answer to 12x12x4 is 576
0.619 cubic yards.
1 cubic meter is 1.308 cubic yards.
440,740.741 cubic yards.
There are approximately 1.30795 cubic yards in a cubic meter.
That is approximately 16.741 cubic yards
11 cubic yards
30,000 (cubic yards) = 22,936.6457 cubic meters
17.8 cubic yards in 480 cubic feet.
2,511 cubic feet = 93 cubic yards.
837 cubic feet = 31 cubic yards.
40 cubic feet = 1.481 cubic yards.
