Date: 4/13/96 at 12:23:30 From: Anonymous Subject: Cubic feet and square feet I need to know how to compute square feet for some cabinets that I have to move in a room. I have computed it by the formula base X height - i.e., the length of the base of one cabinet is 38 inches, with 26 inches as the width. The height is 94 inches. Would I multiply the length times the width and then multiply that figure by the height to find out the square footage for one cabinet? There are nine cabinets in all that I need to move. What's the difference between this and computing the cubic feet for the same nine cabinets and what would the cubic feet be?

Think about a rectangle. It's flat so we don't have to think about its height, and we can think of its area as the length of one side times the length of the other side. Now pretend that the rectangle is the bottom of one of your cabinets. The cabinet could have a very different volume depending on its height. In terms of your question, the square footage of a cabinet isn't well defined unless you specify the face of the cabinet that you're interested in. If you want to know how much floor space the cabinet will take up, we can talk about the square footage (area) of the base of the cabinet being equal to the length times the width of the base of the cabinet. We could also multiply the square footage (area) of the base of a cabinet by the height to get the cubic footage (volume) of the whole cabinet. I hope that this is helpful. -Doctor Aaron, The Math Forum
