Since OC is perpendicular to AB, the line AB gets split evenly. So
So AB=2*6.7=13.4
Ans: Option B, 13.4 units
Is 500/1000 closest to 0, 1/2 or 1

Check the picture below.
so, the diameter of the sphere, is the same as a side's length of the cube, bearing in mind that all sides in a cube are the same length.
since all sides in the cube are "d", then its volume is V = d*d*d or V = d³.

since the diameter is twice as much as the radius, thus d = 2r, or namely d = 18.
therefore, the volume of the cube will be V = 18³.
