Question

What is the sum of the total number of faces of the Square Pyramid and the total number of vertices of Triangular Pyramid?

• A. 5
• B. 6
• C. 8
• D. 9

Answer 1

The correct option is D 9

• In any geometric solid that is composed of flat surfaces, each flat surface is called a face.
• The common endpoint of two or more rays or line segments is known as vertex.

Square Pyramid has 5 faces as we can see in the figure below.

Triangular Pyramid has 4 vertices as we can see in the figure below.


number of faces of Square Pyramid + number of vertices of Triangular Pyramid
=5+4
=9
