Question

Verify Euler's formula for the solid.

Answer 1

Euler's formula for solids $\Rightarrow$ Faces$+$ Vertices$-$ Edges $=2$

The given solid in the image is a Cuboid

$\therefore$ Faces of the cuboid $=6$

Vertices$=8$

Edges $=12$

putting these values in Euler's formula $\Rightarrow 6+8-12=2$

Hence, Verified.
