1.	The volume of a cube is 216 m3 then its edge is ……………. mts. A) 22 B) 16 C) 9 D) 6
Answer» Correct option is (D) 6 Let edge of a cube be a meter. \(\therefore\) Volume of cube is \(V=a^3m^3\) But given that volume of cube is \(216\,m^3.\) \(\therefore\) \(a^3=216=6^3\) \(\Rightarrow\) a = 6 Therefore, edge of given cube is 6 m. Correct option is D) 6

The volume of a cube is 216 m3 then its edge is ……………. mts. A) 22 B) 16 C) 9 D) 6

Answer»

Correct option is (D) 6

Let edge of a cube be a meter.

\(\therefore\) Volume of cube is \(V=a^3m^3\)

But given that volume of cube is \(216\,m^3.\)

\(\therefore\) \(a^3=216=6^3\)

\(\Rightarrow\) a = 6

Therefore, edge of given cube is 6 m.

Correct option is D) 6
