Answer 1

Answer:

Step-by-step explanation:

1.centroid

2.orthocentre

3.circumcentre

4.incentre

5.cube

6.According to the formula given by Euler.

F + V = E + 2

Where,

F = no. of faces

V = no. of vertices

E = no. of edges

So,

=> 20 + 12 = E + 2

=> 32 = E + 2

=> E = 32 - 2

=> E = 30

edges =30

7.f+v=E+2

f+6=12+2

f=14-6

f=8

faces=8

8. similarily vertices =6

9. prism

10.4
