Answer:
36 inches
Step-by-step explanation:
We know that Kelly's little brother is exactly 3 feet tall, and we know how big he is in inches.
To solve first keep in mind that 1 feet is 12 inches.
Therefore if there are 3 feet, we would multiply the inches 3 times.
12 * 3
= 36
Therefore, Kelly's little brother is 36 inches.
