Volume of small objects may be expressed in cubic inches or cubic centimeters.
This example problem demonstrates how to convert cubic inches to cubic centimeters.
Many small car engines have an engine dispacement of 151 cubic inches. What is this volume in cubic centimeters?
1 inch = 2.54 centimeters
First, convert to cubic measurements
(1 inch)3 = (2.54 cm)3
1 in3 = 16.387 cm3
Second, convert to cubic centimeters
Set up the conversion so the desired unit will be cancelled out. In this case, we want cubic centimeters to tbe the remaining unit.
volume in cm3 = (volume in in3) x (16.387 cm3/1 in3)
volume in cm3 = (151 x 16.387) cm3
volume in cm3 = 2474.44 cm3
A 151 cubic inch engine dispaces 2474.44 cubic centimeters of space.
