Answer:

  • C. 440 in²

Step-by-step explanation:

Area of top and bottom faces:

  • 2(10*10) = 200 in²

Area of front and back faces:

  • 2(10*10 - 8*5) = 2(100 - 40) = 2(60) = 120 in²

Area of left and right faces:

  • 2(10*10 - 8*5) = 2(100 - 40) = 2(60) = 120 in²

Total surface area:

  • S = 200 + 120*2 = 440 in²

Correct choice is C
