Find the surface area of a cuboid 17 m long, 8 m broad and 3 m high.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 422 m2
The surface area of a cuboid = 2 × (BL + LH + HB) where , H = height, L = lenght and B = breadth
⇒ Surface area = 2 × (8 × 17 + 17 × 3 + 3 × 8)
⇒ Surface area = 2 × ( 136 + 51 + 24) = 2 × (211) = 422 m2
