Which of the following 3D shapes can be formed by folding the given 2D net?
To determine which 3D shape can be formed by folding the given 2D net, let's analyze the structure of the net:
- The net shows a square base with four triangular flaps attached to each side of the square.
- When folding this net, each triangular flap will rise up and meet at a single point above the base.
- This arrangement of a square base and four triangular faces meeting at a single point is characteristic of a pyramid.
Therefore, the correct 3D shape that can be formed is a pyramid.
Let's examine why other options do not fit:
- Cube: A cube requires six square faces, which this net does not provide.
- Cuboid: A cuboid also involves rectangular faces and does not match the triangular and square combination of the net.
- Tetrahedron: A tetrahedron is made up of four triangular faces, but this net has a square and four triangles, not suitable for forming a tetrahedron.
Thus, the only correct answer is a pyramid.
