• If a US gallon has a volume of 0.134 ft³ and a human mouth has a volume of 0.900 inch³, then how many mouthfuls of water are required to fill a 5.00 US gallon can?

• Answer:

5 US gallon = 5 x 0,134 = 0,67 ft³
0,67 ft³  = 1157.76 inch³
1157.76 in³ / 0.900 inch³  = 1286,4 mouthfuls ≈ 1,29 x 10³ mouthfuls
