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
You don't. You either A) convert 18 cubic inches into cubic feet, or B) convert 18 square inches into square feet. A... there are 1728 cubic inches in a cubic foot, so 18 cu in would be 0.00104 cu ft. B... there are 144 square inches in a square foot, so 18 square inches would be 0.125 sq ft.
Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.Since a foot has 12 inches, a cubic foot has 123 cubic inches, equal to 1728 cubic inches.
The units are incompatible. Cubic measurements are for volume, square measurements are for area.
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.
