The following questions are based on the information given below:
How many small cubes have only one face coloured ?
Answer: Option D
Explanation:
Number of small cubes having only one face coloured = (x - 2)2 x No. of faces
= (4 - 2)2 x 6
= 24
How many small cubes have no faces coloured ?
Answer: Option B
Number of small cubes having only one faces coloured = (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 coloured ?
Number of small cubes having three faces coloured = No. of corners = 8
How many small cubes are there whose two adjacent faces are coloured red ?
Number of small cubes having two adjacent faces coloured red = (x - 2) x No. of edges
= (4 - 2) x 12
