Volume is the amount of space occupied by a three-dimensional object. The metric system uses liters (l) or cubic centimeters (cc or cm3). The Imperial system uses gallons and quarts for “wet” volume and cubic feet for “dry” volume. You’ll need to determine volume any time you fill a vehicle’s reservoir with liquid. This includes petrol/gasoline, coolant, oil, transmission fluid, or lubricant.
