• answer is 56
  8 corners and
  there are 4 cubes between 2 corner cubes on each edge
  total 12 edges so its 4*12 = 48
  
  total = 8+48 = 56

• No of cubes painted only 2sides is= 12((N-2n)/n)
  here N=6
  n=1
  so the answer is = 12((6-2)/1)
  =12(3)
  =36

• Ans:44
  Here they asked that atleast 2 means that 2 and 3
  For 2 sides 12*(n-2) =12*(6-3)=36
  For 3 sides 8 (Fix for any cube)
  Then answer is 36+8=44
