Answer:
48 5/6 square miles
Explanation:
You want the surface area of a rectangular prism with dimensions 6 mi, 2 1/3 mi, and 1 1/4 mi.
Area
The area is given by the formula ...
A = 2(LW +H(L +W))
Using the given dimensions, this is ...
A = 2(6·(2 1/3) + (1 1/4)(6 + 2 1/3)) = 48 5/6 . . . . square miles
The surface area is 48 5/6 square miles.
