The total surface area of a closed cube is given as 1152 cm2. What is the length (in cm) of each side of the cube?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. .
Let the length of each side of the cube be x cm.
So, 6x2 = 1152
⇒ x2 = 1152/6 = 192
⇒ x = √(192) = 8√3 cm
