Question 1

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 24 visible faces.

Question 2

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 18 visible faces.

Question 3

A standard die (opposite faces sum to 7) is shown from different angles: View 1: Top: 1 Front: 2 Right: 3 Which face is opposite to face 1?
Using the standard dice rule (opposite faces sum to 7):
- From the views, we can determine adjacency relationships
- Face 1 appears in multiple views
- Tracking orientations shows it is opposite to 6 (since 1 + 6 = 7)

Question 4

If you assemble these 2D shapes in 3D space by joining matching edges, which 3D shape do you get? Parts: ▲ + ▭ + ▲
The triangular prism can be constructed from:
triangle, rectangle, triangle arranged appropriately.
This is a standard net/assembly pattern for a triangular prism.

Question 5

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.

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.

Question 7

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 8

A standard die (opposite faces sum to 7) is shown from different angles: View 1: Top: 1 Front: 2 Right: 3 Which face is opposite to face 1?
Using the standard dice rule (opposite faces sum to 7):
- From the views, we can determine adjacency relationships
- Face 1 appears in multiple views
- Tracking orientations shows it is opposite to 6 (since 1 + 6 = 7)

Question 9

If you assemble these 2D shapes in 3D space by joining matching edges, which 3D shape do you get? Parts: ▲ + ▭ + ▲
The triangular prism can be constructed from:
triangle, rectangle, triangle arranged appropriately.
This is a standard net/assembly pattern for a triangular prism.

Question 10

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.

Question 11

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 17 visible faces.

Question 12

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

Question 13

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

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 15

The cube can be constructed from:
square, square, square, square, square, square arranged appropriately.
This is a standard net/assembly pattern for a cube.

Question 16

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): ⬜ ⬜ ⬜
