**Question:**  
If you know the volume of an object in cubic inches, can you find its volume in cubic feet by dividing by 12? Explain your answer.

**Explanation:**

When converting volume from cubic inches to cubic feet, dividing by 12 is not sufficient. This is because there are 12 inches in a foot, and volume conversions require cubing this conversion factor, since volume is a three-dimensional measurement.

To convert cubic inches to cubic feet, you need to divide by \(12^3\), which is 1,728, not 12. This is because:

1 foot = 12 inches, so:
1 cubic foot = \(12 \times 12 \times 12 = 1,728\) cubic inches.

Thus, to convert the volume of an object from cubic inches to cubic feet, you divide by 1,728, not 12.
