Question 1

How many distinct nets (ignoring rotations and reflections) fold into a cube?

Accepted Answer

11

Answer

Exactly 11 of the 35 hexominoes fold into a cube.

Question 2

In a straight row of three squares within a cube net, which two squares end up as opposite faces?

Accepted Answer

The first and third

Answer

Squares separated by exactly one square in a straight line fold onto opposite faces.

Question 3

Which shape can NEVER appear inside a valid cube net?

Accepted Answer

A 2x2 block of squares

Answer

A 2x2 block would place four faces around one vertex, but a cube vertex joins only three faces.

Question 4

A net has four squares in a row with one extra square attached above the first square and one above the fourth. What happens when it is folded?

Accepted Answer

Two flaps overlap and one face is left open

Answer

Both flaps land on the same side of the loop, overlapping as the top while the bottom stays open.
