Question

Find the number of faces, edges and vertices of pyramid with square base. Verify

Euler’s formula for it.​

Answer 1

By visualising or seeing an image, you will find that it has 5 vertices,5 faces and 8 edges.

Verification

V-E+F=2

LHS

V-E+F=2

⇒ 5-8+5=2

Now ,

(5+5)-8=2 [By using Associative property]

⇒2=2=RHS

(Hence verified )
