Answer:
372cm2
Step-by-step explanation:
[tex](9.5 \times 5 + 5 \times 8 + 9.5 \times 8) \times 2[/tex]
You solve in the brackets first (but also follow orders in the operations!
I'll just break it down:
[tex](9.5 \times 5) + (5 \times 8) + (9.5 \times 8)[/tex]
The answers you'll get are 47.5, 40, and 76; add them together and you get 163.5!
Lastly, you multiply 163.5 by 2, which the answer is 327cm2, so the surface are equals 372cm2!
