    13 feet and 2 inches.

    Step-by-step explanation:

    First, I would add all the feet together. 3 + 5 + 3 = 11 feet. Now we're going to leave that to the side and solve the inches. 10 + 11 + 7 = 28 inches. But, you need to divide it by 12 because there are 12 inches in one foot. So, 28/12 = 2 feet and 2 inches. Add the 11 feet back with the 2 feet, which equals 13 feet. Bring in the 2 inches, and that gives us our final answer, which equals 13 feet and 2 inches.
