Question

verify Euler's formula of (1) square pyramid (2) trangular prism (1)Rectangular prism

Answer 1

square pyramid
faces 5
vertices 5
edges 8
f+v=e+2
5+5=8+2
10=10

triangulation prism
faces 5
vertices 6
edges 9
5+6=9+2
11=11

rectangular prism
faces 6
vertices 6
edges 10
6+6=10+2
12=12 .

hope it helps you

Answer 2

hii!!

here's ur answer...

we know to verify by Euler's formula in which F+V-E=2.

1. square pyramid

→faces = 5
→verticies = 5
→edges = 8

verification:-

= F+V-E
= (5+5)-8
= 10-8
= 2

hence verified

2. triangular prism

→faces = 5
→verticies = 6
→eges = 9

verification:-

= F+V-E
= (5+6)-9
= 11-9
= 2

hence verified

3. we know that rectangular prism is a cuboid.

→faces = 6
→verticies = 8
→edges = 12

verification:-

= F+V-E
= (6+8)-12
= 14-12
= 2

hence verified

hope this helps u..!
