The surface area of the design is 197 in².
Solution:
Area of the front face =
= 35 in²
Area of back face =
= 35 in²
Area of left side face = base × height
= 5 × 5
= 25 in²
Area of top face = base × height
= 5 × 5
= 25 in²
Area of bottom face = base × height
= 9 × 5
= 45 in²
Area of right side face = base × height
= 5 × 6.4
= 32 in²
Surface area of the design = 35 + 35 + 25 + 25 + 45 + 32
= 197 in²
The surface area of the design is 197 in².
Option D is the correct answer.
