Q. A cube has numerically equal volume and surface area. The volume of such a cube is
A) $216\ units$
B) $1000\ units$
C) $2000\ units$
D) $3000\ units$
Explanation
Volume of cube =$\ a^{3}$ Surface area of cube = ${6a}^{2}$ according to problem $a^{3}\ = 6a^{2} \Rightarrow a = 6$ $\therefore V = a^{3} = 216\ units$
