i don't  quite understand how to convert them.

There are three feet in one yard.

anonymous · Answer

so 3 yards and 2 feet?

campbell_st · Answer

well leave them as improper fractions

3ft = 1 yard

and 36 inches = 1 yard 

so its

11/3 x 11/3 x 3/36 = 

then multiply the answer by 63 to find the cost
