In a cube f + v = ……………. A) 14 B) 16C) 19 D) 20

1.	In a cube f + v = ……………. A) 14 B) 16C) 19 D) 20
Answer» Correct option is (A) 14 In a cube number of edges (E) = 12. By Euler's relation, we know that F + V - E = 2 \(\Rightarrow\) F + V = E + 2 = 12+2 = 14 Alternate :- Number of faces in a cube is F = 6, Number of vertices in a cube is V = 8. \(\therefore\) F + V = 6+8 = 14 Correct option is A) 14

Answer»

Correct option is (A) 14

In a cube number of edges (E) = 12.

By Euler's relation, we know that

F + V - E = 2

\(\Rightarrow\) F + V = E + 2 = 12+2 = 14

Alternate :- Number of faces in a cube is F = 6,

Number of vertices in a cube is V = 8.

\(\therefore\) F + V = 6+8 = 14

Correct option is A) 14
