There's no way to find the mass with the information given. "200 ft" and "875 ft" are linear dimensions ... things you would measure with a ruler. They tell us how long or wide or high the TV is. None of that information tells us anything about its mass.
By the way ... those are gigantic measurements. I was working in Wrigley Field here in Chicago just before opening day in 2015, when the new video screens were being installed. I saw them up close while the cranes lifted them into position. None of the Chicago Cubs' new screens is as big as the numbers in the question, and I'm pretty sure the whole score-board isn't that big either. Something is definitely wrong here.
I will need more info to tell you the mass of the tv but with the info that you give me all that i can do is multiply them which turns out to be 175,000 is the surface area of just one side
You probably can't read my hand writing but I spent like, 15 minutes on this. This is the correct answer, but I don't know how to explain how it is but I promise it is!
