Respuesta :

Okay so first I am going to calculate the surface area for each shape:
Square: 18*18= 324
-Since there are 2 squares (1 in front and 1 in back) we multiply 324*2= 648

Triangle: (18*12)/2= 108
-Since there are 8 triangles (4 in front and 4 in back) we multiply 108*8= 864

Rectangle: 15*3= 45
-And since there are 8 we multiply 45*8= 360

And finally you add all of the results together:
648+864+360= 1872
So the ANSWER is: 1872 square inches
