Question

Using Euler’s formula find the unknowns.
Faces=? , vertices=6, edges=12​

Answer 1

Answer:

8 Faces.

Solution:

Euler's Formula:

$\large \underline{\boxed{\rm{ Face + Vertices = Edges + 2}}}$

• Vertices = 6
• Edges = 12
• Let Faces = x

⠀

According to Euler's formula:

⟹⠀Faces + Vertices = Edges + 2

⟹⠀x + 6 = 12 + 2

⟹⠀x + 6 = 14

⟹⠀x = 14 - 6

⟹⠀x = 8

⠀⠀⠀⠀⠀⠀⠀⠀⠀

The number of faces of the polyhedron = x = 8

know more:

Euler's formula is only applicable for polyhedrons. A polyhydron is a three dimensional figure ( 3-D). it has it faces as polygons. Edges are straight lines and vertices are sharp corner.

A polygon is a two dimensional figure or a plane figure. which has its sides as straight lines.
