ATDH Perceptual Ability: Spatial Relations (Pattern Folding)

Question 1

How many squares does a flat pattern (net) need to fold into a closed cube?

Accepted Answer

6

Answer

A cube has 6 faces, so its net must have exactly 6 squares connected edge to edge.

Question 2

Which arrangement of six squares CANNOT be folded into a cube?

Accepted Answer

Six squares in a single straight row

Answer

In a straight row of six, the first four squares wrap around to form a loop. The fifth and sixth then land on faces already used, so the top and bottom are never closed. The other three arrangements are valid cube nets.

Question 3

A cross-shaped net has a vertical column of four squares labeled A (top), B, C, D (bottom). Square E is attached to the left of B and square F to the right of B. When folded into a cube, which face is opposite B?

Accepted Answer

D

Answer

The four squares in the column wrap around to form a loop. In that loop, squares two apart are opposite each other: A is opposite C, and B is opposite D.

Question 4

Using the same cross-shaped net (column A–B–C–D, with E left of B and F right of B), which face is opposite E?

Accepted Answer

F

Answer

E and F attach to opposite sides of B. When folded, they become the left and right walls of the cube, which are opposite each other.

Question 5

In a cube net, squares 1, 2 and 3 lie in a straight line, edge to edge. When the cube is folded, how are squares 1 and 3 related?

Accepted Answer

They are opposite faces

Answer

Squares 1 and 3 each fold 90° from square 2 in opposite directions. They end up parallel to each other on opposite sides of the cube.
