  1. In a cube net, face P is surrounded on all four sides by faces Q, R, S, and T. Face U is the only remaining face not directly touching face P. In the folded cube, face U is:

    Answer: Directly opposite face P

    All four neighboring positions around face P are filled by Q, R, S, and T, so U is the only face that can sit directly opposite P.

  2. In a cube net that includes a straight row of 4 squares, the squares at each end of the row will become what relationship in the finished cube?

    Answer: Opposite faces

    In a straight row of 4 squares, the two end squares fold around to face each other, always becoming opposite faces of the cube.

  3. Two squares in a cube net are separated by exactly one square between them along any path. In the finished cube, these two squares are:

    Answer: Either adjacent or opposite, depending on the net layout

    Squares separated by one square can become either opposite or adjacent faces — the overall net layout determines which.

  4. A flat net for an open-top box (no lid) consists of one square base and four rectangular sides. How many faces does the finished open box have?

    Answer: 5

    An open-top box has 5 faces: 1 bottom and 4 sides — the 6th face (the lid) is absent.

  5. A cube net made of 6 equal squares is rearranged into a different valid net also made of 6 equal squares. The cubes produced by folding each net will be:

    Answer: Identical cubes of the same size

    Any valid cube net made of 6 equal squares always folds into a cube of the same size — the layout affects face arrangement, not cube dimensions.

  6. A 3D shape has exactly 4 triangular faces and no other face types. What shape is it?

    Answer: Tetrahedron

    A tetrahedron has exactly 4 equilateral triangular faces and is the only common polyhedron with 4 identical triangular faces.

  7. A net shows 2 large congruent rectangles and 4 smaller rectangles. When folded into a rectangular prism, the 2 large rectangles become:

    Answer: The largest pair of opposite faces

    The two identical large rectangles must form the largest pair of opposite faces regardless of which direction they face in the finished box.
