The figure 12.3 has ________ vertices, __________ edges and __________ faces
Solution:
We know that
Vertex is the point where two or more lines or edges meet to form an angle.
An edge is a line segment on the boundary joining one vertex (corner point) to another.
A face refers to any single flat surface of a solid object.
So the figure has 10 vertices, 15 edges and 7 faces.
Therefore, the figure has 10 vertices, 15 edges and 7 faces.
✦ Try This: How many vertices, edges and faces are present in a cone?
We know that
Vertex is the point where two or more lines or edges meet to form an angle.
An edge is a line segment on the boundary joining one vertex (corner point) to another.
A face refers to any single flat surface of a solid object.
A cone does not have any edges.
So the cone has 1 vertex and 1 face.
Therefore, a cone has 1 vertex and 1 face.
