Question

Can someone please help me with 32?

Answer 1

I know that writing it out helps me out. So draw a cube with all of the side lengths. Find the surface area of the whole cube which should be 433.5. Then find the surface area of the portion that is painted yellow which should be 216.75 and subtract them. That's the portion that's painted red. 

Hope this helps!

Answer 2

The answer would be 216.75. I am not very sure, as it could be another answer. But, this is what I did.
A = 6a(power of 2)
then divided that by half to get the red answer. I really hope this helps you! Have a great day!
