Given:

Fuel volume: 3800 US Gallons
Fuel density: 0.79 kg/l

The Fuel Mass is…

  • A

    14 383 kg.

  • B

    18 206 kg.

  • C

    11 364 kg.

  • D

    13 647 kg.

First we change from US gallon to litres:
1 US gallon = 3.785 Litres
3800 US gallon = 3800 x 3.7855 = 14 385 litres

Mass = volume x density
Fuel Mass = 14 385 x 0.79 = 11 364 kg
