A V6 engine with a per-cylinder displacement of 529 cubic centimeters has what approximate total displacement when rounded up?

A V6 engine with a per-cylinder displacement of 529 cubic centimeters has what approximate total displacement when rounded up?

• A. 3.0 L
• B. 3.2 L
• C. 2.6 L
• D. 3.4 L

Answer: (B)

Total displacement is found by multiplying the per-cylinder displacement by the number of cylinders. Here, 529 cm^3 per cylinder times six cylinders equals 3174 cm^3, which converts to 3.174 liters (since 1000 cm^3 = 1 L). Rounding to one decimal place gives 3.2 L, so the approximate total displacement is about 3.2 L. The other options are farther from 3.174 L: 3.0 L would be 3000 cm^3, 3.4 L would be 3400 cm^3, and 2.6 L would be 2600 cm^3.
