Not enough info. I would expect to be given the length of the other horizontal. Then it would be easy.

Yes, it not possible to get the value of X. link

BTW, is it possible?

Yes it is possible to calculate but check whether all the information is required or not . I think some information is missing .

I don't really know, but it only gave me the radius.I'll check again later

@I'm a Malaysian! – If we know the length of the chord we can easily find the answer.

@Ram Mohith – 2nd cord?

@I'm a Malaysian! – Yes the chord above the diameter

@Ram Mohith – It says the second cord is the bottom of an imaginary square and the surface area of two connected in form of up and down cube created with the imaginary square is 50.
