Comment from student: A new sidewalk will be 6 ft wide, 160 ft long, and filled to a depth of 3 inches (0.25 foot) with concrete.
How many cubic yards of concrete are​ needed?


My response: O, I see great progress in your writing. Now I can read and solve it. 

The sizes of the sidewalk are: 

    the length = 160 ft =  yards;
    the width  =   6 ft =  = 2 yards;
    the depth  =   3 in =  =  yard.


Now the volume is  =  = 8.889 cubic yards.
