# How many square inches in a cubic inch?

There can be no equivalence. A square inch is a measure of area in 2-dimensional space while a cubic foot is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed. Study guides

A cubic foot is equal to a cube that has a length, width, and height that's equal to 1ft each. Assuming that you are asking the square inches of a single side of a cubic foot, you can determine the square inches of a side by simply converting 1ft into inches. In this case, since 1ft = 12 inches, the area can be calculated by multiplying 12x12, which would give you 144 square inches None. A square foot is length times width whereas a cubic inch is length times width times height. Invalid conversion: square inches is a measure of area and cubic inches is a measure of volume. Their is no way to figure out this for cubic is a term in math for volume and square is a term used for the area and surface area. They are two different things.  Earn +20 pts
