Hi there!
Let's work through this in pieces. First, let's start with the bases, which would be 2(4 x 5). Next, let's do the left and right sides, which would be 2(5 x 10). Lastly, we'll find the front and back sides, which would be 2(4 x 10). Now, all we have to do is add the expressions together.
WORK:
2(4 x 5)
2(20) = 40
2(5 x 10)
2(50) = 100
2(4 x 10)
2(40) = 80
40 + 100 + 80 = 220
ANSWER:
The fourth option - 220in^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
