Step-by-step explanation:
Lateral Surface area = 2 height(length + breadth)
= 2. (8) (16 + 12)
= 16 × 28
= 448 cm²
Total Surface area = 2 (Length x Breadth + breadth x height + Length x height)
= 2 [ (16).(12) + (12).(8) + (16).(8) ]
= 2 [ 192 + 96 + 128 ]
= 2 × 416
= 832 cm²
Lateral Surface Area of Cuboid = 448 cm²
Total Surface Area of Cuboid = 832 cm²

- Length of the cuboid = 16 cm.
- Breadth of the cuboid = 12 cm.
- Height of the cuboid = 8 cm.
- Total surface area ( TSA ) of the cuboid
- Lateral surface area ( LSA ) of the cuboid
