Reasoning and answer: Bill needs 2 * 3 = 6 gallons of color paint for the 3 bedrooms. Thus, he needs 6 / 1 = 6 cans of color paint for the bedrooms. There are 2 * 3 = 6 other rooms in the house. He needs 2 * 6 = 12 gallons of white paint for the other rooms. Thus, he needs 12 / 3 = 4 cans of white paint. In all, Bill needs 4 + 6 = 10 cans of paint for the whole house.
The answer: 10
