Show Answer Key & Explanations Step-by-step solution for: 3d Shapes Worksheets
To solve the problem, we need to analyze each 3D shape and determine the number of faces that are squares, triangles, or rectangles. Let's go through each shape step by step.

Shape 1: Cube


- Question: How many square faces?
- Analysis: A cube has 6 faces, and all of them are squares.
- Answer: More than one

Shape 2: Tetrahedron


- Question: How many triangle faces?
- Analysis: A tetrahedron is a pyramid with a triangular base and three triangular sides. It has 4 faces, and all of them are triangles.
- Answer: More than one

Shape 3: Cylinder


- Question: How many rectangle faces?
- Analysis: A cylinder has two circular faces (top and bottom) and one curved surface. The curved surface is not a polygon, so it does not count as a rectangular face.
- Answer: None

Shape 4: Rectangular Prism


- Question: How many rectangle faces?
- Analysis: A rectangular prism has 6 faces, and all of them are rectangles.
- Answer: More than one

Shape 5: Square Pyramid


- Question: How many square faces?
- Analysis: A square pyramid has a square base and four triangular faces. So, it has 1 square face.
- Answer: One

Shape 6: Triangular Prism


- Question: How many triangle faces?
- Analysis: A triangular prism has two triangular bases and three rectangular sides. So, it has 2 triangular faces.
- Answer: More than one

Shape 7: Cone


- Question: How many triangle faces?
- Analysis: A cone has a circular base and a curved surface. The curved surface is not a polygon, so it does not count as a triangular face.
- Answer: None

Final Answer:


\[
\begin{array}{|c|c|c|c|c|}
\hline
\text{Shape} & \text{Question} & \text{None} & \text{One} & \text{More than one} \\
\hline
1 & \text{How many square faces?} & & & \checkmark \\
\hline
2 & \text{How many triangle faces?} & & & \checkmark \\
\hline
3 & \text{How many rectangle faces?} & \checkmark & & \\
\hline
4 & \text{How many rectangle faces?} & & & \checkmark \\
\hline
5 & \text{How many square faces?} & & \checkmark & \\
\hline
6 & \text{How many triangle faces?} & & & \checkmark \\
\hline
7 & \text{How many triangle faces?} & \checkmark & & \\
\hline
\end{array}
\]

The final answer is:
\[
\boxed{
\begin{array}{|c|c|c|c|c|}
\hline
\text{Shape} & \text{Question} & \text{None} & \text{One} & \text{More than one} \\
\hline
1 & \text{How many square faces?} & & & \checkmark \\
\hline
2 & \text{How many triangle faces?} & & & \checkmark \\
\hline
3 & \text{How many rectangle faces?} & \checkmark & & \\
\hline
4 & \text{How many rectangle faces?} & & & \checkmark \\
\hline
5 & \text{How many square faces?} & & \checkmark & \\
\hline
6 & \text{How many triangle faces?} & & & \checkmark \\
\hline
7 & \text{How many triangle faces?} & \checkmark & & \\
\hline
\end{array}
}
\]
