26 inches

I don't get the second part
You add up the height off all the stacked boxes together. easiest to start with the inches first, 7+10+9 which is 26 inches. simplify that to 2 feet 2 inches. Then add the feet, 3+3+4 which is 10. Add the two sums together. So, the answer would be 12 feet and 2 inches
