Three boxes are stacked one on top of the other. One box is 3 feet 5 inches tall, one is 5 feet 11 inches tall, and one is 4 feet 9 inches tall. How high is the stack? Write your answer in feet and inches. Use a number less than 12 for inches.

14 ft. and 1 in. (14' 1")

Step-by-step explanation:

First, you add all of the feet together.

3 + 5 + 4 = 12 ft.

Next, add all of the inches.

5 + 11 + 9 = 25 in.

Because 12 inches is equal to 1 foot, we need to divide 12 into 25, which gives us 2 ft. and 1 in.

But that's not all. Lastly, you need to put everything together.

12 + 2 = 14 ft, and 1 in.

Hope this helps.
