Suppose that a white Rubik's Cube is painted blue on top and bottom and painted red on the four lateral sides. The cube is then separated into its 27 smaller cubes.

How many unit cubes have at least one red face and one blue face?

The houses on River Road are numbered consecutively from 10 to 132. Each house number is made with brass digits.

#105 would take 3 digits, for example.

1. How many brass digits are needed to form all the house numbers?

2. The numbers can be purchased for 2.29 each or $20.95 per dozen (of the same digit). What is the cheapest combination of numbers that you can arrange?
