Question

Verify Euler’s formula for the following solids and draw their nets.

(i) Regular tetrahedron.

(ii) Octahedron prism.​

Answer 1

Answer:

Euler's formula for solids ⇒ Faces+ Vertices− Edges =2

The given solid in the image is a Cuboid

∴ Faces of the cuboid =6

Vertices=8

Edges =12

putting these values in Euler's formula ⇒6+8−12=2

Hence, Verified.
