RRB Group D Cube & Dice

Identify which faces are opposite to each other in the net.

Faces that are separated by exactly one face in between are opposite.

In the net A-B-C-D, face A is opposite to face C (one face B in between).

Face E is above B, so E is opposite to F (which is below C).

Face B is opposite to face D.

Since A is at bottom, its opposite face C will be at top. Answer: Face C For Dice Problems: Remember the standard dice pattern: 1 opposite 6, 2 opposite 5, 3 opposite 4. If you see faces 1, 2, 3 meeting at a corner, you know 6, 5, 4 meet at the opposite corner. Cube Cutting Formula: If a cube is cut by n planes parallel to faces: Total pieces = (n₁ + 1) × (n₂ + 1) × (n₃ + 1), where n₁, n₂, n₃ are cuts along length, breadth, and height. Common Mistake: Students often confuse adjacent faces with opposite faces. Remember - opposite faces never appear together in any single view of a cube. If two faces are visible together in a view, they cannot be opposite faces.
