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 !
