Answer:
4. 23 in
Step-by-step explanation:
The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.
1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.
Add 8 inches to 15, and you get 23 inches.
<u>The answer is 4. 23 in. </u>
