Answer:
440 [tex]in^2[/tex]
Step-by-step explanation:
Find the area of each of the faces and add them all up
bottom: (10)(10) + (10)(2) + (10)(2) + (5)(10) + (5)(5) + (10)(2) + (10)(2) = 255 [tex]in^2[/tex]
top: (5)(8) + (5)(8) + (5)(8) + (5)(8) + (5)(5) = 185 [tex]in^2[/tex]
255 + 185 = 440 [tex]in^2[/tex]
