a hollow cube of 5cm is taken with a thickness of 1cm,it is made of smaller cubes of size 1cm if 4 faces of the outer side of the cube are painted totally how many faces of the smaller cube remain unpainted?

• Correction:
  Faces of smaller cube painted = 4*5*5 = 100
  Total no. of small cubes = 5*5*5-3*3*3 = 98
  Total faces of small cubes = 6*98 = 588
  Unpainted faces of smaller cube = 588-100 = 488

• Faces painted = 6*5*5 = 150
  Total no. of small cubes = 5*5*5-3*3*3 = 98
  Total faces of small cubes = 6*98 = 588
  Unpainted faces of smaller cube = 588-150 = 438
