A T is made of two identical 740 g thin solid rods. The moment of inertia of the T about an axis perpendicular to the screen through point at one end of a rod is determined experimentally to be 0.68 kg-m2. What is the length of the rods?

I have no idea where the screen is. But I suspect you need the parallel axis theorem.

The answer depends upon which end of which rod is the axis of rotation. You have not provided that information. Is it there the rods intersect? Or the bottom of the "T" ?

the bottom of the T or at the top of an inverted T
