If each edge of a

Answer :

(i) ∵ Surface Area of a Cube  SA= 6(Side)2
If Side is doubled then New Surface Area,
SA' = 6(2
      = 4× 6(Side)2
      = 4 × SA
∴ SA of new Cube will be 4 times of SA of Original Cube.

(ii) ∵ Volume of a Cube V= (Side)3

If Side is doubled then New Volume of Cube,
V'= (2× Side)3
   = 8× (Side)3 
   = 8× V
∴ Volume of new Cube will be 8 times the Volume of Original Cube.
