**Problem:**

Many small car engines have an engine dispacement of 151 cubic inches. What is this volume in cubic centimeters?

**Solution:**

1 inch = 2.54 centimeters

First, convert to cubic measurements

(1 inch)

^{3}= (2.54 cm)

^{3}

1 in

^{3}= 16.387 cm

^{3}

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 cm

^{3}= (volume in in

^{3}) x (16.387 cm

^{3}/1 in

^{3})

volume in cm

^{3}= (151 x 16.387) cm

^{3}

volume in cm

^{3}= 2474.44 cm

^{3}

**Answer:**

A 151 cubic inch engine dispaces 2474.44 cubic centimeters of space.
