Credit Repair Help

The problem reads:

You have a square birthday cake that is 10″by 10″by 2″ deep. The cake is frosted on the top and sides. You plan to share the cake among five people (including yourself). How can you divide the cake so that each person gets exactly the same amount of frosting?

Please explain your answer. And just so you know my teacher doesn’t consider this cheating as long as I give your brilliance credit, so make sure to leave your name =]

Thanks!

Balls are drawn from a bag initially containing three white balls and five black balls. At each drawing two balls are drawn at random. If both drawn balls are the same color they are set aside and the game continues by drawing two more balls from those remaining in the bag. If at any stqge the two drawn balls are of different colors, the game ends. What is the expected number of bqlls drawn during a game? –Please give an explanation of how to get the answer.

I have an extra credit problem for math and I have tried to solve it and cannot get past this one step.

If the sum of two numbers is 1 and the sum of the cubes of the numbers is 3, what is the sum of the squares of the numbers? (fractional answer, no decimals)

So I made two equations.

a+b=1
a^3+b^3=3

I have tried substitution and everything and I cannot get it.
