Conversion means representing some quantity in terms of different units; since square inches measure an area, and cubic inches measure a volume, they can't represent the same quantity. So there's no way to convert one to the other. But there are other things you can do. Presumably you have some situation in which some area is RELATED to some volume. If we know what that relationship is, we can find one from the other. For example, if the area is the area of a garden, and the volume is the amount of mulch to be spread over it 3 inches deep, then the relationship is that the volume of the mulch (thought of as a cuboid or a cylinder) is the base area times the height, so V = Bh = (3 in) * (567 in^2) = 1701 in^3 Note that there is no way for me to do this without knowing, first, the fact that the area is the base of a cylinder (the general relationship), and, second, the height of that cylinder (additional measurement relevant to that relationship). Can you fill in the gaps in your question? - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/
