To solve this problem, we need to identify the 3D shape that is formed when each flat "net" is folded up. A net is a pattern that you can cut out and fold to make a solid figure.
Here is the step-by-step breakdown for each number:
1.
Shape: This net has 6 squares arranged in a cross shape. When you fold the four side squares up and put the top one on, it makes a box with all equal sides.
*
Answer: Cube
2.
Shape: This net has 6 rectangles. It looks like a stretched-out version of number 1. When folded, it makes a box shape where the sides are rectangles, not squares.
*
Answer: Rectangular Prism
3.
Shape: This net has a square in the middle and four triangles attached to the sides. If you fold the triangles up, they meet at a single point at the top. This creates a pyramid with a square base.
*
Answer: Square Pyramid
4.
Shape: This net has three rectangles in a row and two triangles on the top and bottom. The triangles form the ends (bases), and the rectangles fold around to connect them. This is a prism named after its base shape.
*
Answer: Triangular Prism
5.
Shape: This net has five rectangles in a strip and two pentagons (5-sided shapes) on the top and bottom. Since the bases are pentagons, it is a pentagonal prism.
*
Answer: Pentagonal Prism
6.
Shape: This net has six rectangles in a strip and two hexagons (6-sided shapes) on the top and bottom. Since the bases are hexagons, it is a hexagonal prism.
*
Answer: Hexagonal Prism
7.
Shape: This net has a square in the center and four triangles attached to every side. Like number 3, these triangles fold up to meet at a point. Because the base is a square, it is a square pyramid.
*
Answer: Square Pyramid
8.
Shape: This net consists of four identical triangles connected together. When folded, it forms a pyramid with a triangular base. This specific shape is often called a tetrahedron, but in general geometry classes, it is classified by its base.
*
Answer: Triangular Pyramid
Final Answer:
1. Cube
2. Rectangular Prism
3. Square Pyramid
4. Triangular Prism
5. Pentagonal Prism
6. Hexagonal Prism
7. Square Pyramid
8. Triangular Pyramid
