Question Analysis

This question involves identifying a 3D object based on its net. The main focus is on spatial reasoning and understanding how 2D nets translate into 3D structures.

 

Key Concept Explanation:

A net is a 2D pattern that can be folded to form a 3D shape. Different 3D shapes have distinct net patterns.

 

Option Analysis

The net has two triangular faces and three rectangular faces.

This matches the structure of a triangular prism: two bases (triangles) and lateral faces (rectangles). As the bases in the net are triangles, this net represents a triangular prism.

Therefore, the correct answer is D.

 

The other options are incorrect:

Option A: A rectangular prism has all rectangular faces, so this option is incorrect as the net has triangular faces.

 

Option B: A cube has 6 square faces, so thi...
