Team Careers360 · Accepted Answer

Correct Answer: $864$ cm²

Solution : Given: Radius of the sphere, $r= 6\sqrt3$
Diagonal of the cube = diameter of sphere $=2×r=2×6\sqrt3=12\sqrt3$
We know that,
Edge of the cube, $a= \frac{ ext{Diagonal length}}{\sqrt3}=\frac{12\sqrt3}{\sqrt3} = 12$
$ herefore$ Total surface area of the cube $=6a^2=6×12^2= 864$
Hence, the correct answer is $864$ cm².
