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.
From first figure to second figure the four circle located outside the large circle come inside the circle. Therefore, from third figure to the answer figure the four inner line segments would move outside the square.
NA
From the first figure to the second figure the middle design rotates through 90° and moves to the extreme right position after being reduced in size and the lower most design encloses the inverted and reduced upper most design.
As per the given above question figure ,
Figure ( 2 ) of the answer figures is exactly the mirror image of the given original image . Thus , Given image will become opposite in mirror across the given line .So , option B is correct figure .
As per the given above question figure ,
Figure ( 3 ) of the answer figures is exactly the mirror image of the given original image . Thus , Given image will become opposite in mirror across the given line MN.So , option C is correct figure .
