Question

What is the sum of the number of faces, vertices and edges of a cuboid?

• A. 18
• B. 22
• C. 26
• D. 20

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.

Cuboid has 6 Faces, 8 Vertices and 12 Edges.

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