Explanation:

Step1: Recall cube - net properties

A cube has 6 square faces. The net of a cube is a 2 - D shape that can be folded to form a 3 - D cube. The correct net of a cube should have 6 congruent square faces arranged in a way that they can be folded to form the cube.

Step2: Analyze the options

The first option has 6 congruent square faces with side - length 30 cm and is in a valid arrangement for a cube net. The second option has 7 square faces, which is incorrect as a cube has only 6 faces.

Answer:

The first diagram (the one with 6 congruent 30 - cm by 30 - cm squares arranged correctly)
