To build a wall that is 6 feet high by 200 feet long using bricks measuring 16 inches by 8 inches, you would need approximately 1340 bricks. For mortar, a rough estimate suggests needing around 3 cubic yards based on the total brick count, but it’s best to consult with a professional for accurate requirements.
