Reasoning and answer: First find the volume of the sand in one jug: 2 gallons * 70% = 1.4 gallons. Then double this amount since there are two jugs: 1.4 gallons * 2 = 2.8 gallons. Then multiply the total volume by the density of sand to find the total weight: 2.8 gallons * 5 pounds / gallon = 14 pounds.
The answer: 14
