Identify the Correct Net Pattern: Cube Unfolding Analysis

To determine which figure represents an unfolded cube, we need to ensure the following:

• The figure must consist of exactly 6 squares.

• The squares must be connected along their edges to allow the figure to fold into a cube without overlapping.

Let's examine each of the choices:

• Choice 1: This figure consists of 6 squares arranged in a "T" shape. By folding the squares, we can form a cube, which is a valid unfolded cube shape.

• Choice 2: This figure consists of only 5 squares, which is insufficient to form a cube.

• Choice 3: This figure also has 6 squares, but the arrangement will not form a cube since the squares aren't in a connected format that allows a full enclosure.

• Choice 4: This figure consists of 7 squares, having an extra square, which invalidates it as a cube net.

Therefore, after examining all options, we conclude that Choice 1 is the correct one, as it can be folded into a cube.
