If a cube is inscribed inside a sphere then the diagonal ( longest side) of the cube is equal to the diameter of the sphere?

the formula for diagonal of a cube is D = $$\sqrt{3}$$a

Is this correct? Can I apply this strategy for such questions?

Don't understand what you mean by the red parts: longest side in a cube? Also what do you mean by "such questions"?

Other than that all is correct.

I was referring to the diagonal of the cube as the longest side...

An example of this question would be cube is inscribed inside in a sphere. Volume of sphere is provided and we have to find the surface area of the cube?

An edge (side) of a cube is not the same as diagonal.
