All you need to do is calculate the area of each side and add them together.  If you need a nudge with that let me know.

jim_thompson5910 · Answer

You can also use the formula

SA = 2*(LW + WH + LH)

where

SA = surface area
L = length
W = width
H = height

i am sorry what ???

jim_thompson5910 · Answer

where are you stuck?

jim_thompson5910 · Answer

the formula for the surface area of a box with length L, width W and height H is 

SA = 2*(LW + WH + LH)

jim_thompson5910 · Answer

in your case

the length is 12, so L = 12
the width is 8, so W = 8
the height is 2, so H = 2

jim_thompson5910 · Answer

which means

SA = 2*(LW + WH + LH) 

turns into

SA = 2*(12*8 + 8*2 + 12*2) 

after you plug the given info in
