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
