Question

What is the sum of the total number of faces, vertices, and edges of a Rectangular Prism?

• A. 22
• B. 24
• C. 26
• D. 28

Answer 1

The correct option is C 26

• In geometry, an Edge is where two faces meet in an object.
• The common endpoint of two or more rays or line segments is known as Vertex.
• In any geometric solid that is composed of flat surfaces, each flat surface is called a Face.

So, Rectangular Prism has 8 Vertices, 12 Edges and 6 Faces.

$\therefore$ Number of Edges + Number of Vertices + Number of Faces
= 12 + 8 + 6
= 26
