Carla is dividing up chores for her two kids, Anna and Billy. She wants each of them to spend the same number of minutes working. Sweeping takes 3 minutes per room, washing the dishes takes 2 minutes per dish, and doing laundry takes 9 minutes per load. If Anna does the sweeping for 10 rooms and Billy does two loads of laundry, how many dishes should Billy wash so they spend the same amount of time doing chores? Let's think step by step and output the final answer after "####".

First find the total time Billy spends on laundry: 2 loads * 9 minutes/load = <<2*9=18>>18 minutes
Then find the total time Anna spends sweeping: 3 minutes/room * 10 rooms = <<3*10=30>>30 minutes
Then find how much longer Anna has already worked than Billy: 30 minutes - 18 minutes = <<30-18=12>>12 minutes
Then divide the difference in work time by the time to wash one dish to find the number of dishes Billy has to wash to work the same amount of time as Anna: 12 minutes / 2 minutes/dish = <<12/2=6>>6 dishes
