Homework Help Thursday 9-5-13

If you are stuck with math homework tonight, please remember:

1. Every Arrangement will always have one cube in the center.

2. There are always 5 arms.

3. There is always 1 less than the arrangement's name in each arm.

So... if it is the 4th arrangement, it will have 1 cube in the middle, 5 arms, and each arm will have 3 because it is one less than the arrangement's name, which is 4.

1+3+3+3+3+3=16 or 1+ (5x3)=16
