If a V6 engine has 529 cubic centimeters per cylinder, what is the approximate engine displacement after rounding to the nearest tenth of a liter?

If a V6 engine has 529 cubic centimeters per cylinder, what is the approximate engine displacement after rounding to the nearest tenth of a liter?

• A. 3.0 L
• B. 3.2 L
• C. 3.4 L
• D. 3.6 L

Answer: (B)

Engine displacement is found by totaling the volume of all cylinders. A V6 has six cylinders, each with a displacement of 529 cubic centimeters. Multiply 529 by 6 to get 3174 cubic centimeters. Since 1 liter equals 1000 cubic centimeters, 3174 cc is 3.174 liters. Rounding to the nearest tenth of a liter gives 3.2 liters, because the hundredths place is 7, which pushes the tenths place up from 3.1 to 3.2. So the approximate displacement is 3.2 L.
