A shape that covers an area A and has a uniform heighth has a volume V = Ah. (a) Show that V = Ah is dimensionallycorrect. (b) Show that the volumes of a cylinder and of arectangular box can be written in the form V = Ah, identifyingA in each case. (Note that A, sometimes called the “footprint”of the object, can have any shape and that the height can, ingeneral, be replaced by the average thickness of the object.)

Question
A shape that covers an area A and has a uniform height
h has a volume V = Ah. (a) Show that V = Ah is dimensionally
correct. (b) Show that the volumes of a cylinder and of a
rectangular box can be written in the form V = Ah, identifying
A in each case. (Note that A, sometimes called the “footprint”
of the object, can have any shape and that the height can, in
general, be replaced by the average thickness of the object.)
