Question

Write the number of 'Faces, edges and vertices' of each shape has:
Cylinder
Cone
Pentagonal
Pyramid
Hexagonal pyramid
Hexagonal prism
Pentagonal prism

Answer 1

Step-by-step explanation:

In the question,

i) Cylinder: Cylinder is the shape which is a pipe like structure having curved surface and circular top and bottom.

Faces - 3 (curved - 1, plane - 2)

Edges - 0 (curved edges 2)

Vertices - 0

ii) Cone: Cone is the shape with the curved surface from the top in the shape of a triangle is viewed in 2D from front and has a circular base.

Faces - 2 (curved - 1, Plane - 1)

Edges - 0 (curved - 1)

Vertices - 1

iii) Pentagonal: Pentagonal shape is a 2D shape and is completely plane.

Faces - 1  

Edges - 5

Vertices - 5

iv) Pyramid: Pyramid is a 3D shape and has only plane surfaces.

Faces - 5

Edges - 8

Vertices - 5

v) Hexagonal Pyramid: Hexagonal pyramid is a 3D shape with the base as Hexagon.

Faces - 7

Edges - 12

Vertices - 7

vi) Hexagonal Prism: It is also a 3D shape and the base is Hexagon.

Faces - 8

Edges - 18

Vertices - 12

vii) Pentagonal Prism: It is a 3D shape with the base as a Pentagon.

Faces - 7

Edges - 15

Vertices - 10

Answer 2

Cone has 1 Vertex

Step-by-step explanation:

3 Faces, 2 Edges and 0 vertices are there with Cylinder

Cone has 2 Faces, 1 Edges and 1 vertex.

Hexagonal Pyramid  6 Faces, 12 Edges and 7 vertices.

Pentagonal Pyramid  5 Faces, 8 Edges and 5 vertices.

8 Faces, 18 Edges and 12 vertices are present in Hexagonal Prism  

7 Faces, 15 Edges and 10 vertices are present in Pentagonal Prism

And

5 Faces, 8 Edges and 5 vertices are there in Pyramid
