Question

The King's courtroom has a staircase containing 1234 stairs. If each step is 12 inches tall, how tall is the entire staircase?

• A. 14,574 in
• B. 14,808 in
• C. 14,042 in
• D. 14,276 in

Answer 1

The correct option is B 14,808 in

Height of each stair $=12in$.

Total number of stairs in the staircase $=1234$.

So, total height of the staircase will be:
$=1234\times 12in$.

Calculating $1234\times 12$ 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, $1234\times 12=14,808$.

Therefore, the total height of the staircase is $14,808inches$.
