so you do 14 x 2 = 28 x 2 = 56
then 14 x 11 =154 x 2 = 308
then 11 x 2 = 22 x 2 = 44
then 44+ 308 + 56 = 408
so the answer is 408\(in^{2}\)

Data:
lenght=2 ft=2ft (12 in/ft)=24 in
width=14 in
heigth=11 in

Surface area of a rectangular prim=2(lenght x width)+2(lenght x height)+2(width x height)

Surface area=2(24 in
14 in)+2(24 in 11 in)+2(14 in 11 in)=
=672 in²+528 in²+ 308 in²
=1508 in²

Answer: 1508 in²
