Question

1. Two dice are placed side by side with 4+3, what is the total on the face opposite to the given
numbers
b) 7
c) 11
d) 6
(a) 3

2. What will be the number of faces if there are 6 vertices and 12 edges?
b)10
d) 18
(a) 8
c)12

3. What will be the number of edges if there are 12 vertices and 20 faces?
b)28
d)42
(a) 32
c)30
3. Which of the following is Euler's Formula:
(c)F-V=E-2
(bF +V=E-2
(dF- V + E =2
(a) F +V-E=2​

Answer 1

Answer:

1. (b) 7

Face opposite to 4 is 3 and face opposite to 3 is 4

therefore, the sum is equal to 4+ 3 = 7

2. (a) 8

Octahedron

3. (c) 30

F + V = E + 2

20 + 12 = E + 2

32 = E + 2

E = 32 - 2

= 30

4. (b) F + V = E - 2
