Total surface area of a cuboid = 2(lb + bh + lh). Here lb=472, bh=72, and lh=531. So TSA = 2 × (472 + 72 + 531) = 2150 square cm. A cuboid has three pairs of equal rectangular faces: lb, bh, and lh. We add these three face areas and multiply by 2 to include the opposite faces. The answer is in square units, so the correct choice is 2150 cm².
