I think I may have gotten it. I divided the shape up. So I did 7*5*7 and got 245. And then did 12*5*5 and got 300 and added 245 and 300 and got C. IDK if it's correct though.

OpenStudy (anonymous):

Oh I got A.. I did 12*12*2 + 12*5*2 and I got 408

OpenStudy (anonymous):

Where did you get 245 from?

OpenStudy (anonymous):

I split the left side of the shape up by taking 7 away from the 12, but IDK if I did that right.

@satellite73, Help us, please?

OpenStudy (anonymous):

I have to go. :( I'm really sorry. I tried to help. :(...

OpenStudy (anonymous):

Thanks for trying! It was actually 458

OpenStudy (anonymous):

You're welcome! And I guess we both got it wrong. :/ At least we tried.

OpenStudy (anonymous):
