Answer: Surface Area equals 352 inches squared.

Step-by-step explanation:

To find the surface area, use the surface area formula, [tex]A=2(wl+hl+hw)[/tex]

With w = 8, h = 4, and l = 12:

[tex]A=2(wl+hl+hw)\\A=2((8*12) + (4*12)+(4*8))\\A=2(96+48+32)\\A=2(176)\\A=352[/tex]

Surface Area equals 352 inches squared
