Question

please ans this and correct by euler's formula....and if u know then only answer​

Answer 1

Answer:

(i) Number of faces in square pyramid =5(f)

Number of vertices =5(v)

Number of edges =8(e)

Verification :

f - e + v = 2

=>5 - 8 + 5=2

=>10 - 8 =2

=> 2=2

verified.

It can also solve by using formula ;

f + v = e + 2

5 + 5 = 8 + 2

10 = 10

(ii) Verified

Step-by-step explanation:

Euler’s formula

F + V = E + 2

Here number of faces = 5

Number of vertices= 6

Number of edges = 9

=5+6=9+2

11=11

(iii) No of faces =6

No of vertices =8

No of edges =12

F+V=E+2

6+8=12+2

14=14
