The size of a television screen is measured by the length of the diagonal.
How big a television would you need to have to have a screen that was just larger than the Mona Lisa?
Is it 37 inches, 42 inches, 50 inches, 60 inches, 70 inches, or 85 inches?
You would need a 37 inch TV to be larger than the Mona Lisa.
It’s not actually that big. Though it’s probably more valuable than a 37 inch TV.
