Total surface area of a cuboid = 2(lb + bh + lh). Here lb=424, bh=88, and lh=583. So TSA = 2 × (424 + 88 + 583) = 2190 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 2190 cm².
