Solution

## The correct option is B 14,808 inHeight of each stair =12 in. Total number of stairs in the staircase =1234. So, total height of the staircase will be: =1234×12 in. Calculating 1234×12 using the standard algorithm process, we get: Step 1: Multiplying 1234 by 2, we gte 2468 as the result. Step 2: Multiplying 1234 by 10, we get 12340 as the result. Step 3: Finally, adding 2468 to 12340, we get the final answer as 14808. So, 1234×12=14,808. Therefore, the total height of the staircase is 14,808 inches.
