I need help please, I worked on solving this one with Dbzfan836  now he is not online , 
and I didn't reach any of the given choices although I did it correctly

anonymous · Answer

we got the SA of the figure  =  [L*W+L*H+H*W]*2 = 4848  
after knowing that   L=36  W=26    H=24
so I divided the SA by (15*15) =  21.546

which is not included in the choices , any help please?
