The total inches of board needed to make 6 birdhouses is 27 inches/birdhouse * 6 birdhouses = 162 inches.

To find how many yards that is, we divide 162 by 36 (the number of inches in a yard): 162/36 = 4.5 yards.

However, since we can't have half of a yard, we round up to the nearest whole yard, giving us the final answer of:

C. 4 1/2 yards.
