If the areas of three adjacent faces of a cuboid are 5 cm2, 15 cm2, 27 cm2, respectively, the surface area of the cuboid is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 94 cm2.
The areas of the three adjacent faces of a cuboid are 5 cm2, 15 cm2, 27 cm2.
Surface Area = 2(5 + 15 + 27)
= 2 × 47
= 94 cm2
So, the surface area of the cuboid is 94 cm2.
