Answer:
912 (AND MAKE SURE YOU ADD YOUR YOUR UNITS!)
Step-by-step explanation:
So both side panels are 10 × 12, and the back glass is 12 × 18.
So we are going to do:
2 × (10 × 12) + 12 × 18
= 240 + 216
= 456
But because of the surface area formula we must multiply this by 2!
456 × 2
= 912
So your answer is 912 and whatever your unit is!
