Question 1

This is the net of a cube with letters on each face: [A][B][C] [D] [E] [F] What is opposite to face A after folding?
By mentally folding the net:
- Identify which edges join when folded
- Track the 3D adjacency relationships
- F ends up opposite to the asked face based on the folding pattern.
cube, folding, pattern, 3d

Question 2

A standard die (opposite faces sum to 7) is shown from different angles: View 1: Top: 2 Front: 3 Right: 5 Which face is opposite to face 3?
Using the standard dice rule (opposite faces sum to 7):
- From the views, we can determine adjacency relationships
- Face 3 appears in multiple views
- Tracking orientations shows it is opposite to 4 (since 3 + 4 = 7)

Question 3

If you assemble these 2D shapes in 3D space by joining matching edges, which 3D shape do you get? Parts: 6 × ⬜
The cube can be constructed from:
square, square, square, square, square, square arranged appropriately.
This is a standard net/assembly pattern for a cube.
assembly, 2d-to-3d, construction

Question 4

How many visible faces can be seen from the front view of this 3D arrangement (assuming each small cube has 6 faces, and cubes are placed on a ground plane, looking from a corner angle)? Cube arrangement (top view, 1=cube present): ⬜ ⬜ ⬜ ⬛ ⬜ ⬛
Each cube has 6 faces, but faces are hidden where cubes touch or touch the ground.
- Count visible faces: Top faces (1 per visible cube) + Front faces + Side faces.
- For this configuration, the total is 22 visible faces.

Question 5

A 3D structure is made of unit cubes. From the front, top, and side views: Front view (looking from front): ⬜⬜⬜ ⬜⬜⬛ ⬜⬛⬛ Top view (looking from above): ⬜⬜⬜ ⬜⬜⬛ ⬛⬛⬛ Side view (looking from right): ⬜⬜⬛ ⬜⬜⬛ ⬛⬛⬛ How many cubes are in the structure (including hidden ones)?
By reconstructing the 3D arrangement from the three orthographic views:
- Each view shows the maximum cubes in that direction
- The intersection of views reveals cube positions
- Total unique cube positions = 9 cubes

Question 6

Which of the following nets can be folded into a cube (without overlapping)?
A valid cube net must have exactly 6 squares connected edge-to-edge, with each square adjacent to at most 4 others, and when folded, all squares meet at edges without overlap.
This net is one of the 11 known cube nets.
