Find the surface area (in m2) of a cuboid that is 11 m long, 7 m broad and 4 m high.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 298.
Given that, length of cuboid = 11 m
Breadth of cuboid = 7 m
Height of cuboid = 4 m
Surface area of cuboid = 2(lb + bh + hl)
According to the given question,
Surface area = 2(11 × 7 + 7 × 4 + 4 × 11)
⇒ 2(77 + 28 + 44)
⇒ 2 × 149 = 298
Hence the surface area of the cuboid (in m2) is 298.
