Well that really depends on the size of the engine. All 12 valve engines are not the same size. Small engines are measure in cc. Auto engines are measured in liters or cubic inches.

cc or cubic centimeters are measuring units that gives an indication of the engine displacement . so it dose not depend on the number of cylinders
you can calculate engine displacement easily by using cylinder volume equation
radius^2*pi*hight
