Answer 1

The tank decreases by 10 gallons every 3 hours. There are 24 hours in a day, and 3 hours is one-eighth of a day. So, in a day, the tank decreases by 10*8 = <<10*8=80>>80 gallons.
After 6 days, the total change in the amount of water in the tank is 6*80 = <<6*80=480>>480 gallons.
The correct answer is 480 gallons.
