Answer:

Surface area = 144 mi.²

Step-by-step explanation:

Surface area of the triangular prism = bh + (P)L

Where,

b = base of triangular base = 6 mi.

h = height of triangular base = 8 mi.

P = Perimeter of triangular base = 10 + 8 + 6 = 24 mi.

L = height of the prism = 4 mi.

Plug the values into the formula

Surface area = 6*8 + (24)4

= 48 + 96

= 144 mi.²
