Question

plsss faster as u can plssss it is very important plssss​

Answer 1

Answer:

As per Euler's formula, Faces+ Vertices = Edges + 2

Using this formula,

(a) E = 12

(b) F = 7

(c) V = 4

(d) E = 9

(e) E = 18

(f) E = 12

Answer 2

Answer:

(a) Edges= 12

(b) Faces=7

(c) Vertices=4

(d) Edges= 9

(e) Edges=18

(f) Edges=12

Step-by-step explanation:

You can check it by using Euler's formula which is V-E+F=2 or F+V=E+2.

Hope it helps...
