A student wishes to determine the thickness of a rectangular piece of aluminum foil but cannot measure it
directly. She can measure its density (d), length (l), mass (m) and width (w). Which relationship will give the thickness?<spanclass=′latex−bold′>(A)</span>d⋅l⋅wm<spanclass=′latex−bold′>(B)</span>dm⋅l⋅w<spanclass=′latex−bold′>(C)</span>md⋅l⋅w<spanclass=′latex−bold′>(D)</span>l⋅wd⋅m
