Question

which of these nets could be folded along the dotted segments to form a cube?
choose the correct answer(s) below

Explanation:

Step1: Recall cube net properties

A cube net has 6 square faces. The common valid cube nets are of specific patterns like the "cross" pattern, the "stair - step" pattern etc.

Step2: Analyze each option

• Option a: This is a valid cube net. It can be folded such that each face meets another face at an edge to form a cube.
• Option b: This is a valid cube net (a type of "stair - step" pattern). When folded, the square faces will enclose a three - dimensional cube.
• Option c: This is not a valid cube net. If we try to fold it, we will find that there will be overlapping or non - closure issues.
• Option d: This is not a valid cube net. The shape of the non - square (arrow - like) parts means it cannot form a cube (a cube has only square faces).

Answer:

A. Option a, B. Option b
