Question

a cube is shown below. which diagram is a net for the cube?

Explanation:

Step1: Recall cube - net properties

A cube net is a 2 - D shape that can be folded to form a 3 - D cube. A cube has 6 square faces of equal size. The most common cube - net patterns are in the form of a cross - like shape with 6 squares attached in a way that they can be folded to enclose a volume.

Step2: Analyze the given diagrams

Both of the given diagrams consist of 6 squares of side - length 28 mm. However, a correct cube net should be able to fold into a cube without any overlapping or mis - fitting of the squares. A standard cube net has a pattern where each square is adjacent to other squares in a way that allows for proper folding. The first diagram is a correct cube net as it has the typical cross - like structure with 6 equal - sized squares that can be folded to form a cube. The second diagram has an extra square which is not part of a valid cube - net structure for a single cube.

Answer:

The first diagram (the one with a typical cross - like pattern of 6 equal squares) is a net for the cube.
