The question is: Two brick walls are being built. Each wall has 30 bricks in a single row and there are 50 rows in each wall. How many bricks will be used to make both walls?
Step-by-step reasoning process: Each brick wall needs 30 x 50 = 1500 bricks. Thus, the two walls need 1500 x 2 = 3000 bricks.
