Answer 7

Oh crap.

Answer 8

Here...

Answer 9

Find the area of the front face of the I (double it since there's also the back face)


Now lets find the other pieces...

Answer 10

Thank you for putting your time into helping me dude.

Answer 11

Crap, middle one should be 1x1 not 2x2.

So the front face is 5x2 + 5x2 + 1x1... double it to get the back as well.

Answer 12

Keep answering! But i'll be back in less then 5 minutes! Bathroom break.

Answer 13

So the front face was 10+10+1=21.
The hard part is keeping track of all the other pieces, and it's not easy to show them all here, so you'll just have to try to follow:

very top part = 5x2 = 10
the five side parts (theres 5 side pieces total, all are 2x2) = 5x2x2 = 20

Remember you have to double both those too, those are only one side of the I...but lets just double it all at the end to make it easier.

Front face+top part+five side parts = 21+10+20
Just double that number.

Answer 14

Crap... the middle one of the front face was 2x1 so the front face is 22.

22+10+20 = 52, double that is 104 and hopefully i haven't missed anything else.

Answer 15

Yeah I got 104 too.

Answer 16

don't forget cm^2

Answer 17

Oh crap true.

Answer 18

THANK YOU SO MUCH! I've been stuck on this for like an hour! I don't have anyone at my house, so I don't have anyone to help me. Thanks so much dude. It's really nice of you to put your time into helping me.

Answer 19

No prob. I kinda didn't want to do it at first, because these surface area problems are always tedious... 2D drawings of 3D objects, ugh, having to try to imagine all the other hidden sides in your head.

Answer 20

Yeah dude i feel ya.
