3D lookup table

A 3D lookup table is like a regular table or chart, except that it has 3 dimensions instead of two. This makes it easier to visualize and understand data, since you can see the relationships between different sets of information more clearly. For example, if you had a 3D lookup table that showed the cost of buying different size packages of apples, oranges, and pears, then you could easily see which package was the best deal. It would be like looking at a cube with different colors filling in each side - each color representing a different size and type of package.
