Question

A cube is painted
blue on two adjacent
faces. It is painted
brown on the faces
opposite to
blue
faces and yellow on
the remaining faces.
After being cut into
sixty-four smaller
cubes of equal size,
what is the fraction
of the cubes which
one
have exactly
face painted blue?​

Answer 1

Answer:

In the figure there are 36 cubes 32 of which are of the same size and 4 others are of bigger size Clearly each side of bigger cubes is twice as large as that of smaller cubes Also since no face of any of the larger cubes is painted blue so each one of the larger cubes has one face painted red one face painted black and all other faces unpainted

There are no cubes having more than three faces painted 8 cubes at the edges of the block have three faces painted and as calculated above 20 cubes have two aces painted Thus 8+20=28 cubes have two or more faces painted.
