Answer 1

Hi,
   
1 cubic yard = 27 cubit feet
 
Then we must find the no. of cubic yards .... for 1 cubic yard = $98 for "x" cubic yard = $58.07 1/x =98/58.07 x = 0.5925
 
Now we have to convert this in to cubic feet... 1 cubic yard = 27 cubic feet 0.5925 cubic yard = x cubic feet 1/0.5925= 27/x x = 15 .99

cubic feet now width x height x length = 16 cubic feet w x 8 x (1/3) = 16 w = 48/8 = 6 feet yep!


there for the width of the yard is approximately 6 feet.. hope this will help ya !
