The correct option is C Equal to the side of the cube

The side length of a cube = AD = a

The diagonal length of a cube = AG =

a √ 3 DF = AG = CE = a √ 3

The triangle formed was an equilateral triangle.

The circumradius of an equilateral triangle =

s √ 3 3

Therefore, the circumradius of that triangle =

a √ 3 √ 3 3 = Side of a cube Suggest Corrections 0 SIMILAR QUESTIONS

Dear Shubham, Circumradius=a*b*c/4A for a triangle, where a,b,c are sides and A is its area. Hence the answer to the above question is "x". The side of the triangle as you found out is √ 3* x. Hope this helps. :)
