A "cubic foot" is a measure of volume (three dimensional), while "square inches" is a measure of area (two dimensional), so the two measurements can't be equated.
In 2D: there are 144 square inches in one square foot.
In 3D: there are 1728 cubic inches in one cubic foot.

"Cubic inch" is a unit of capacity or volume ... the space that an object occupies.
"Square foot" is a unit of surface area ... like the size of a rug or a corn-field.
The two units have different physical 'dimensions', they're used to measure completely different
kinds of quantities, and neither one can be converted to the other one. That would be like trying
to convert your age from years into acres or gallons.
Although the above is correct, another answer is: One over infinity.A square foot does not contain cubic inches because it is a flat square; a cubic foot contains cubic inches in which case L x W x H gives you 1,728 cubic inches in a cubic foot. 12 x 12 x 12 = 1,728
The units are incompatible. Cubic measurements are for volume, square measurements are for area.
1728 cubic inches.
1728 cubic inches.
First, a square is a two-dimensional form, a cube is three-dimensional, and feet is a lineal measurement, ie., one-dimension, so no number of feet will ever equal a square or a cube. An inch is 1/12 of a foot. A square inch is 1/144 of a square foot. A cubic inch is 1/1728 of a cubic foot.
