A cube is divided into 4 equal cubes. Each of these cubes is further sub-divided into 4 equal cubes.Then what is the ratio of the surface area of the smallest cube as a percentage of the original cube?

• how its posible to divide cube in 4 equal cube..
  
  it can be posible only by melting it not by cutting it
  
  so we have to do calculation on the the basis of volume

• surface area of soriginal cube = 6x^2
  then surface area of cut cube = 6*x^2 / 16
  now percentage ans = 100/16 % = 6.25%
