First, let's convert feet to yards

 

Remember  3ft  = 1 yd....so divide ft by 3 to get the yards

 

18 feet / 3   =  6 yds

4 inches  = 1/3 ft / 3  =  1/9  yds

 

So....the total volume is

 

(6 yds) x (6 yds )  x (1/9 yds )     =

 

36  x 1/9   =      4 yds^3

 

So....the cost is

 

( 4 yds^3)  x $41  per  yd^3   =   $ 164
