Answer
216 inches
Work Step by Step
6yd = inches
Use the unit fraction $\frac{3 feet}{1 yard}$ to change yard to feet and the unit fraction $\frac{12 inches}{1 foot}$ to change feet to inches. Notice how all the units divide out except inches, which is the unit you want in the answer.
6 yd * $\frac{3 feet}{1 yard}$ * $\frac{12 inches}{1 foot}$ = 216 inch
