Question

How many cubes have at least two faces coloured yellow?

• A. 24
• B. 44
• C. 48
• D. 96

Answer 1

The correct option is B 44

All the edges of the cubes are painted yellow and the remaining portion on each face is painted pink.
Cubes containing edges with vertices, on front & back faces $=16\times 2=32$
Cubes containing edges without vertices, on top & bottom faces$=6\times 2=12$

Total no. of cubes with at least two yellow sides$=32+12=44$.
