To solve this, you must understand how many inches are in a foot and how many feet are in a yard.
3 feet = 1 yard
12 inches = 1 foot
If you have 12 yards, you can multiply that by 3 to convert them to feet.
36 feet + 5 feet + 3 inches
You can then multiply the amount of feet (41) by 12 to find how many inches you have.
41 * 12 = 492 + 3
495 inches total.
