The net on the right unfolds into a cube. Its arrangement of faces, edges, and vertices aligns with the characteristics of a cube, making it the correct answer. Therefore, option A is the correct choice.
The net depicted on the right unfolds into a cube. Each face of the net corresponds to one of the six faces of a cube, and the arrangement of edges and vertices aligns with the cube's geometric structure.
The cube is a three-dimensional object with equal sides and right angles, making it distinct from other options such as rectangular and triangular prisms.
The net serves as a visual representation of how the cube unfolds into a flat shape, showcasing the geometric relationships inherent in the structure of a cube. Therefore, the correct answer is indeed a cube. The appropriate choice is option A.
