Step-by-step explanation:

Surface area is the sum of the faces of all sides, so find the area of all sides and add

Answer 2

Answer:

40 mi²

Step-by-step explanation:

(see attached for reference)

the formula for surface area of a right rectangular prism

= 2(length x width) + 2(width x height) x 2(length x height)

in our case

length = 4 mi

width = 2 mi

height = 2 mi

substituting these values into the equation:

surface area

= 2(length x width) + 2(width x height) x 2(length x height)

=2(4)(2) + 2(2)(2) x 2(4)(2)

= 16 + 8 + 16

= 40 mi²
