What is the volume of a cube that measures one inch on each side?

To find the volume of a cube, you use the formula for volume, which is side length raised to the third power (side length × side length × side length). Since each side of the cube measures one inch, the calculation is:

1 inch × 1 inch × 1 inch = 1 cubic inch.

A cubic inch is a unit of volume that represents a cube with each side measuring one inch. This is the appropriate measurement for volume, especially for solid shapes like cubes.

The other options do not correctly represent the volume of the cube. A square inch quantifies area, not volume; a fluid ounce measures liquid capacity and doesn’t directly apply to solid objects; and a cubic foot refers to a much larger volume measurement, which is not suitable for a cube measuring only one inch on each side. Thus, "cubic inch" accurately describes the volume of the cube.
