Independent: surface area of walls
Dependent: paint used

Basically, independent means that this data should not need to change. Dependent typically depends on what is given in the independent. Looking back at the example, if the surface area of the walls is large, then a lot of paint would be necessary. The opposite would occur for a smaller surface area in the walls.
