| Solid Figures | Faces | Edges | Vertices |
|---|---|---|---|
| Cube | 6 | 12 | 8 |
Explanation:
A cube is a three-dimensional solid with six equal square faces. Each corner where three faces meet is called a vertex. Since it has 6 faces and 12 edges (line segments where two faces meet), it also has 8 vertices.

Directions: Identify which solid figure is described below:
- It has 2 flat surfaces, 0 edges, and 0 vertices.
Answer: Cylinder
Explanation: A cylinder has two flat circular faces and one curved surface. While it might appear to have edges where the circles meet the curved surface, these are not true edges because they are not sharp or straight. It also has no vertices. - It has a flat surface and a curved surface. What solid figure is it?
Answer: Cone
Explanation: A cone has one flat circular base and one curved surface that wraps around and ends in a point. It has one vertex and one edge where the base meets the curved surface. - It has no flat surface, no edge, and no vertex. Which solid figure is it?
Answer: Sphere
Explanation: A sphere, like a basketball or a globe, is perfectly round. It has no flat surfaces, edges, or vertices. Every point on its surface is the same distance from the center. - It has 9 edges and 6 vertices. It has how many faces? What solid figure is it?
Answer: It has 5 faces; it is a Triangular Prism
Explanation: A triangular prism has two triangular bases and three rectangular lateral faces. It has 6 vertices, 9 edges, and 5 faces. - It has 5 faces and 5 vertices. It has how many edges? Which solid figure is it?
Answer: It has 8 edges; it is a Square Pyramid
Explanation: A square pyramid has one square base and four triangular faces. That gives it 5 faces in total. It has 5 vertices (4 at the base and 1 at the top) and 8 edges (4 at the base and 4 joining the top vertex to each base corner).
Explanation
Solid figures, also known as 3D shapes, have specific properties that help us identify them. These properties include the number of faces, edges, and vertices. A face is a flat or curved surface, an edge is where two faces meet, and a vertex is where three or more edges meet.
A cube is a regular solid figure with 6 equal square faces, 12 straight edges, and 8 vertices. It is often used to introduce 3D shapes in math.
A cylinder has two flat circular faces and one curved surface. It lacks sharp edges or corners, which is why it has 0 true edges and 0 vertices. The same applies to a sphere, which is completely round and has no flat surfaces, edges, or vertices. It is the most symmetric solid shape.
A cone has one flat circular face and a curved surface that meets at a single point, making it different from other solids. It has one vertex and one edge.
A triangular prism has 2 triangular faces and 3 rectangular ones, giving it 5 faces, 6 vertices, and 9 edges.
Lastly, a square pyramid has 1 square face and 4 triangle faces, totaling 5 faces. It has 5 vertices and 8 edges. It is a common example used to explain pyramids in geometry.
Understanding these features helps us classify and work with solid shapes in math, science, and even real-life applications like architecture and design.
