First add up all of your inches (6+2+4+5) this equals 17 inches.
Then, convert this into feet. There are 12 inches in every foot, so 17 inches equals 1 foot and 5 inches.
After this, simply add up the feet (3+8+2). This equals 13 feet.
Finally, add 13 feet and 1 foot. This equals 14 feet.
Take your remaining inches (5) and add that after.
Your final answer is: 14 feet and 5 inches, or 14ft and 5in.
Hope this helps!
