Sry ignore me, I don't really know
A square has all of sides equals. So in the bottom of box you have a square 2x2 and the formula for volumen is width*length*thicknes, from the data 2*2*t=200 cubic inches, solve for t=50 inches. Now for an open box you have 4 pieces around the square in the bottom, you add 50+2+50=102 inches, for lenght and width 102inches
7/2x is ur answer since the denominator is the same so you just add the numerators together
I attached a graph of the function for you to look at. For domain and range use what you know, domain is how far it can stretch from left to right, and the range of the function is how far it can go from bottom to top.
