Question:

Find the surface area of a cuboid 17 m long, 8 m broad and 3 m high.

Options:

420 cm²

417 cm²

402 cm²

422 cm²

Correct Answer:

422 cm²

Explanation:

We know that,

Total Surface area of cuboid = 2(lb + bh + hl)

We are given,

Length = 17m

Breadth = 8m

Height = 3m

So,Putting the values in the formula, we get

= 2(17 × 8 + 8 × 3 + 3 × 17)

= 2(136 + 24 + 51) = 2 × 211 = 422 m².
