Question

using euler 's formula find the unknown
faces 6,?
vertices 8,10
edges ?15​

Answer 1

Answer:

1) ans =》12

2) ans =》7

Step-by-step explanation:

1)

Let the number of edges be x

By Euler's formula

6 + 8 = x + 2

14 – 2 = x

x = 12

2)

Let the number of faces be x

By Euler's formula

x + 10 = 15 + 2

x = 17 – 10

x = 7
