Find the surface area of a cuboid 17 m long, 8 m broad and 3 m high.
Answer & explanation
Correct answer: option 4
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.
