Picture in your mind a cube that measures one foot -- that is, one linear foot -- on each edge. That represents a volume equal to one cubic foot. Since one linear foot equals 12 (linear) inches, the cube measures 12 inches wide by 12 inches deep by 12 inches high. To compute the volume in cubic inches, multiply the length, width, and height. So, 12" x 12" x 12" equals 1,728 inches cubed or 1,728 cubic inches.
There are 12 x 12 x 12 = 1728 cubic inches in one cubic foot.

The inch is a unit of length and the cubic foot is a unit of volume. The conversion isn't possible.
Or, if you want, a cubic foot contain 1 728 cubic inches.
There are 1,728 cubic inches in a cubic foot. This is because a cubic foot is the volume of a cube that measures 12 inches on each side (12 x 12 x 12 = 1,728).
144 cubic inches are in 1 cubic foot.
There are 1,728 cubic inches in a cubic foot because a cubic foot contains 12 inches in each dimension (length, width, height), so 12 x 12 x 12 = 1,728 cubic inches.
Since a foot is 12 inches, and a cubic foot is 12 inches on each edge, there are 12 x 12 x 12 = 1728 cubic inches in a cubic foot. This problem uses the volume formula: V = lwh, where l is length, w is width, and h is height.
There are 1728 cubic inches in 1 cubic foot. Therefore, 5 cubic feet would be equivalent to 8640 cubic inches.
There are 144 square inches in a square foot and 1.728 cubic inches in a cubic foot. So you have 7,776 square inches and that would give you 7,776 cubic inches. That would be 4.5 cubic feet.
