  1. Calculate Water Usage: Calculate the total water usage for one person in a month. Each person used 7272 liters of water for showering.
  2. Find Total Family Usage: Multiply the total water usage per person by the number of people in Trevor's family to find the total water usage for the family. 72liters/person×6people=432liters.72 \, \text{l} \text{iters/person} \times 6 \, \text{people} = 432 \, \text{l} \text{iters}.
