The symbol at the bottom of (D) is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
On a cube, a face can never be next to the face opposite it. So the face opposite a symbol is the one symbol that never appears beside it in any of the positions. The face at the bottom of (D) is the face opposite its top, the small square.
The cube has six symbols: the small square (drawn longer on top of A), the square within a square, the small circle, the double circle, the two parallel lines (slanting on B, level on C) and the triangle.
Faces seen beside the small square (top of A, C and D):
Cube (A): the double circle and the small circle
Cube (C): the two parallel lines and the triangle
Four of the other five symbols touch the small square, so the fifth, the square within a square (the top of B), is opposite it. It is therefore at the bottom of (D).
