Let's find the volume of the topsoil.

In our case, the volume is the product of the three dimensions.


2 inch thick is   =   of a foot.  So, the volume of the topsoil is

    V =  = 30.33333333...  cubic feet.


One cubic feet is   =   of a cubic yard.


So, the volume V in cubic yards is  V =  = 1.12345679 cubic yards.


With the increment of 1/4 cubic yard, this volume is between 1 cubic yard and   = 1  cubic yards.


ANSWER.  1  cubic yards of topsoil should be ordered.

Solved.
