Explanation: Number of small cubes which are Black and Green is 8 in all. Hence, the number of remaining cubes are = 24 - 8 = 16 The following questions are based on the information given below:
How many small cubes will have only two faces colored ? Explanation: Number of small cubes having only two faces colored = 6 from the front + 6 from the back + 2 from the left + 2 from the right = 16
Explanation: Such cubes are related to the corners of the cuboid and there are 8 corners. Hence, the required number is 8.
Explanation: Number of small cubes have no face colored = (4 - 2) x (3 - 2) = 2 x 1 = 2
Explanation: Number of small cubes having only one face colored = 2 x 2 + 2 x 2 + 2 x 1 = 4 + 4 + 2 = 10
The following questions are based on the information given below:
Explanation: Such cubes are related to the corners of the cuboid and in the cuboid there are 8 corners. Hence, the required number of small cubes is 8.
Explanation: 2 from the front + 2 from the back + 3 from the left + 3 from the right + 6 from the top + 6 from the bottom = 22
Explanation: Required number of small cubes = (5 - 2) x (4 - 2) x (3 - 2) = 3 x 2 x 1 = 6
Explanation: Required number of small cubes = 6 from the top and 6 from the bottom = 12 The following questions are based on the information given below:
How many small cubes have only one face colored? Explanation: Number of small cubes having only one face colored = (x - 2)2 x No. of faces = (4 - 2)2 x 6 = 24
How many small cubes have no faces colored? Explanation: Number of small cubes having only one faces colored = (x - 2)3 Here, x = side of big cube / side of small cube x = 4 /1
x = 4 Required number = (4 -2)3 = 8 How many small cubes are there whose three faces are colored? Explanation: Number of small cubes having three faces colored = No. of corners = 8
Explanation: Number of small cubes having two adjacent faces colored red = (x - 2) x No. of edges = (4 - 2) x 12 = 24
The following questions are based on the information given below: All the opposite faces of a big cube are colored with red, black and green colors. After that is cut into 64 small equal cubes. How many small cubes are there where one face is green and other one is either black or red ? Answer: Option C
Number of small cubes having one face green and the other one is either red or black = 8 x 2 = 16
A cube is cut in two equal parts along a plane parallel to one of its faces. One piece is then colored red on the two larger faces and green on the remaining, while the other is colored green on two smaller adjacent faces and red on the remaining. Each is then cut into 32 cubes of same size and mixed up.
Explanation: 8 from (I) and 8 from (II) Therefore 8 from each.
Explanation: 24 from (I) and 14 from (II) How many cubes have two red and one green face on each ? Explanation:
None from (I) and 4 from (II) How many cubes have no colored face at all ?
There is no such cube in all, where all the faces are uncolored.
Explanation: 16 from (I) and 8 from (II) There are 128 cubes with me which are colored according to two schemes viz.
64 and 64 cubes of both types of cubes are such who have at least two colored faces red each. Therefore, total number of the required cubes is 128.
No. of red faces among first 64 cubes = 128 No. of red faces among second 64 cubes = 192 Therefore, total number of red faces = 128 + 192 = 320 How many cubes have two adjacent blue faces each ? Second 64 cubes are such each of whose two faces are blue.
Out of 128 cubes no cube have only one face is red
First 64 cubes are such each of whose two faces are green and second 64 cubes are such each of whose two faces are blue. Therefore, green and blue colors have the same number of faces. All the six faces of a cube of a cube are colored with six different colors - black, brown, green, red, white and blue.
Which of the following is adjacent to green ?
Explanation: CHAPTER 13 :QUESTIONS ON CHRACTER PUZZLE: In this type of questions, a figure or a matrix is given in which some numbers are filled according to a rule. A place is left blank. You have to find out a character (a number or a letter) from the given possible answers which may be filled in the blank space.
