What is on the opposite face?

Six squares form a flat cube net. One square has a thicker outline. Fold the net in your head and choose the mark on the face opposite that square. Each mark is on one square.

Help

Six squares form a flat net that folds into a cube. Find the mark on the face opposite the square with the thicker outline.

A useful clue: squares that share an edge in the net remain adjacent faces after folding, so they cannot be opposite. Merely touching at a corner is not the same rule.

The outlined square’s own mark is not offered: a face cannot be opposite itself. The other five marks are offered, and each is on one square.

About this practice

A cube net is six connected squares that fold into the six faces of a cube. Choose Opposite faces to find a hidden face, or Match the cube to compare the net with four folded cubes. In both modes, the net stays visible and there is no time limit.

Opposite faces: a worked example

Find the face opposite the square with the thicker outline. Squares that share an edge in the net stay adjacent after folding, so they cannot be opposite. Squares that do not share an edge may still become neighbours: distance across the flat paper is not enough to decide.

Level 1. Which mark is opposite the outlined dot?

Hold the outlined dot facing you. The four squares touching its edges fold into the four side faces. The last flap, marked with a square, closes the back. Answer: square. Turning the finished cube changes which faces you can see, but not which two are opposite.

Match the cube: a worked example

Choose the one cube that the net can make. First eliminate any choice that puts opposite marks on touching faces. Then check the order of the three visible marks around their shared corner. A rotated cube is allowed; a mirror image is not.

Level 3. Each mark appears on exactly one face.

Which cube can this net make?

  • ACube A. Top: ring. Front, on the left: target. Right: four dots.
  • BCube B. Top: ring. Front, on the left: four dots. Right: dot.
  • CCube C. Top: four dots. Front, on the left: dot. Right: plus.
  • DCube D. Top: plus. Front, on the left: target. Right: dot.
  1. Find the opposite pairs first. On this net they are four dots opposite plus, ring opposite dot and target opposite square.
  2. Cube B shows ring and dot side by side. Opposite faces never touch, so it is out.
  3. Cube C shows four dots and plus side by side. Opposite faces never touch, so it is out.
  4. Cube D shows no opposite pair, but the three marks go round the corner the wrong way. That is a mirror image, and no turn makes it.
  5. That leaves cube A.

What each level changes

  • Levels 1–2: cross-shaped nets, with the net turned at level 2.
  • Levels 3–4: branched nets. In Match the cube, wrong choices start to include mirrored corners.
  • Levels 5–6: strip nets that you follow from one square to the next.
  • Levels 7–8: all eleven cube-net layouts, with flat nets turned or mirrored at level 8.
  • Level 9, Match the cube only: oriented marks. Follow the direction of a triangle, shaded half or diagonal through the fold. The right faces alone are not enough; the mark must also point the right way.

Levels 4 and 6 also turn their nets. Mirroring the flat net at level 8 changes the net you must fold; it does not make a mirror image of that folded cube a valid answer.

What your result means

The score counts correct answers out of 3 to 7 questions, depending on the level. Speed does not affect the score. Compare completed rounds in the same mode and level, and use See how it folds after an answer to check the face relationships. A short round describes those questions, not your overall spatial ability. Ending a round early does not save it.
