None, since there can be no conversion.
A square foot is a measure of area in 2-dimensional space while a cubic yard is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
There can be an infinite amount of square feet in one cubic yard, since square refers to the second dimension, and not the third, like cube does. However, there are 27 cubic feet in one cubic yard.
Base it off : 12" thick a yard of concrete will go 27sqft. 6" thick will go twice as many sqft so 54 sqft. 4" thick will go 3 times as many sqft so 81 sqft 2" thick will go 6 times as many sqft so 162 sqft and at 1" thick it will go 324 sqft. So at 5" thick...1 yard of concrete will go 67.5 sqft
Nine square feet per square yard.
764,600cc per cubic yard.
Based on the category I am assuming we are takling dirt or mulch. 75 yds x 27 cuft (there is 27 cuft per 1 cuyd) = 2,025 cubic feet of material - 1 foot thick would be 2,025 sqft. - 6 inches thick would be 4,050 sqft. - 3 inches thick would be 8,100 sqft.
1 cubic yard is about 0.7646 cubic meters.
There are 27 cubic feet in one cubic yard.
There are 27 cubic feet in one cubic yard.
One cubic yard equates to 764,554,858 cubic millimeters.
1 cubic yard = 27 cubic feet
46,660 cubic inches per cubic yard.
A cubic yard is bigger than a cubic foot. There are 27 cubic feet in a cubic yard.
