A straight concrete sidewalk is to be $3$ feet wide, $60$ feet long, and $3$ inches thick.  How many cubic yards of concrete must a contractor order for the sidewalk if concrete must be ordered in a whole number of cubic yards?
$\text{(A)}\ 2 \qquad \text{(B)}\ 5 \qquad \text{(C)}\ 12 \qquad \text{(D)}\ 20 \qquad \text{(E)}\ \text{more than 20}$
This is a $1$ yard by $20$ yard by $1/12$ yard sidewalk, so its volume in yards is 
\[1\times 20\times \frac{1}{12} = 1.\overline{6}.\]
Since concrete must be ordered in a whole number of cubic yards, we need $2\rightarrow \boxed{\text{A}}$.
