Correct Answer: 384 m 2
Solution : Given: The volume of a cuboid is twice that of a cube and its dimensions are 8 m × 8 m × 16 m. Volume of cuboid = Length × Breadth × Height Let the side of a cube be a. Volume of the cube = a 3 According to the question, 8 × 8 × 16 = 2a 3 $\therefore$ a = 8 m The total surface area of the cube = 6a 2 = 6 × 8 2 = 384 m 2 Hence, the correct answer is 384 m 2 .
