Question

a solid cube painted yellow,blue and black opposite side are of same colour. The cube is then cut into 36 of two different sizes that 32 are small and 4 are big size. None of the faces bigger cube is painted blue. How cubes are painted one face only ​

Answer 1

Answer:

20

Step-by-step explanation:

Size of bigger cubes is twice the size of smaller cubes. Also, as none of the faces of the bigger cubes is painted blue, so each one of the bigger cube has one face painted yellow, one is black and all other faces are unpainted.

Number of cubes with one face painted = 8

Number of cubes with two faces painted = 8 smaller cubes on each of blue painted surface + 4 bigger cubes

= (8 x 2) + 4 = 20
