Choose the net (A, B, C, D or E) that best fits the following 3D figures. Give only the answer. For example: (2,1) A

Here are the matches for the 3D figures and their nets:

• 2.1: Triangular prism A triangular prism has two triangular bases and three rectangular lateral faces. Net E shows three rectangles in a row with two triangles attached to the middle rectangle, which is a standard net for a triangular prism.

  $$\text{2.1} \rightarrow \boxed{\text{E}}$$

• 2.2: Rectangular prism (cuboid) A rectangular prism has six rectangular faces. Net D shows six rectangular faces arranged in a way that forms a cuboid when folded.

  $$\text{2.2} \rightarrow \boxed{\text{D}}$$

• 2.3: Cube A cube is a special type of rectangular prism with six identical square faces. Net A shows six identical squares arranged in a cross shape, which is a classic net for a cube.

  $$\text{2.3} \rightarrow \boxed{\text{A}}$$

• 2.4: Square pyramid A square pyramid has a square base and four triangular faces. Net C shows a square in the center with four triangles attached to its sides, which is a net for a square pyramid.

  $$\text{2.4} \rightarrow \boxed{\text{C}}$$
