A 2012 Dodge Avenger SXT Plus[*] has an engine with a displacement of 3.6 liters. A liter is defined to be the volume of a cube with 100 mm sides. The displacement of the 3.6 liter engine, in units of cubic millimeters is:
(A) 0.036 mm3.
(B) 360 mm3.
(C) 3.6×104 mm3.
(D) 3.6×106 mm3.

Correct answer (highlight to unhide): (D)

Converting 3.6 liters to cubic millimeters, where a liter is equal to the volume:

(100 mm) × (100 mm) × (100 mm) = 106 mm3, then 3.6 liters = 3.6×106 mm3.
