Best answer

Let the side of the cube be “a” unit 

Original Surface area = 6a2 sq units 

Now, when each side of a cube is doubled than its surface area: 

New surface area = 6 (2a2) sq units 

= 24a2 sq units 

Therefore, the surface area of the cube is 4 times than its original area 

Hence, option B is correct
