**Answer:**

161 centimeters

**Step-by-step explanation:**

To find the total height, we need to find the wait of each individual box. Since we have five boxes stacked up on each other with a height of 115, we can divide 115 by 5 to get 23. Now that we know that each box is 23 centimeters tall, we can multiply that by 2 because 2 more boxes were added, and then add that to 115.

115/5=23

23*2=46

46+115=161

Hope this helps!
