  • Question
  • How many of the cubes have 2 faces painted?


  • Options
  • A. 23
  • B. 29
  • C. 44
  • D. None of these

  • Correct Answer
  • 44 

    Explanation

    Out of 6 faces of 5 faces are exposed and those were painted.
    Number of vertices with three faces exposed (Painted) is 4
    Number of vertices with 2 faces exposed (Painted) is 4
    Number of vertices with 1 faces exposed (Painted) is 0
    Number of vertices with 0 faces exposed (Painted) is 0
    Number of sides with 2 sides exposed (Painted) is 8
    Number of sides with 1 sides exposed (Painted) is 4
    Number of sides with no sides exposed (Painted) is 0
    From the above observation:
    Number of cubes with 3 faces Painted is 4
    Number of cubes with 2 faces Painted is given by sides which is exposed from two sides, out of 8 such edges 4 vertical edges will give us 6 cubes per edge and 4 edges from top surface will give us 5 such cubes from each edge and required number of cubes is 6 x 4 + 4 x 5 = 44.
    Number of cubes with 1 face Painted is given by faces which is exposed from one sides four vertical faces will give us 6 x 5 = 30 cubes per face and top face will give us 5 x 5 = 25 and required number of cubes is 30 x 4 + 25 x 1 = 145
    Number of cubes with 0 face Painted is given by difference between total number of cubes - number of cubes with at least 1 face painted = 343 - 4 - 44 - 145 = 150
    In other words number of cubes with 0 painted is 6 x 5 x 5 = 150
    From the above explanation number of the cubes with 0 faces painted is 150.
    From the above explanation number of the cubes with 2 faces painted is 44.
