The weight of 5 gallons of water depends on the temperature because water’s density changes slightly with temperature. However, under standard conditions:
1 gallon of water weighs approximately 8.34 pounds.
Therefore, 5 gallons of water would weigh:
5 × 8.34 = 41.7 pounds.
This calculation assumes the water is at room temperature (around 70°F or 21°C).
