To determine how tall Stumpy's giant stilts are, you only need two pieces of information: Stumpy's normal height and his height with the giant stilts.
The heights you need to consider are:
- Stumpy's normal height: 5 feet 10 inches.
- Stumpy's height with his giant stilts: 14 feet.
From these two pieces of information, you can calculate the height of the giant stilts:
-
Convert Stumpy's normal height to inches:
- 5 feet 10 inches = (5 × 12) + 10 = 60 + 10 = 70 inches.
-
Convert Stumpy's height with giant stilts to inches:
- 14 feet = 14 × 12 = 168 inches.
-
Now subtract Stumpy's normal height from his height with the giant stilts to find the height of the giant stilts:
- Height of giant stilts = 168 inches - 70 inches = 98 inches.
The unnecessary information for answering the problem includes any height related to Stumpy's short stilts because the height of the short stilts is not needed to find out how tall the giant stilts are. Therefore, the unnecessary information is:
Stumpy is 8 feet 11 inches with his short stilts.
