Writing 'Square Foot'Date: 05/05/2001 at 09:30:16 From: Gloria Subject: Symbol for square foot I am looking for a symbol for "square foot." I can't seem to find it anywhere - is there one? Thanks for your time. Gloria Date: 05/05/2001 at 15:05:20 From: Doctor Terrel Subject: Re: symbol for square foot Hi Gloria, Let's pretend you need to say, "The area of the tabletop is 10 square feet." I would prefer that younger students (pre-algebra and below) write "10 sq. ft." Older students may write "10 ft^2" (in e-mail, that is, where we can't do superscripts). When done by pencil, the "2" is written raised and small, like an exponent (but it is NOT an exponent as in "5^2"). It should still be spoken as "10 square feet." The same applies for all square units: sq in or in^2 sq cm or cm^2 When you need volume, it goes like this: SPOKEN cubic feet: cu ft ft^3 cubic inches: cu in in^3 cubic centimeters: cu cm cm^3 Glad to help. - Doctor Terrel, The Math Forum http://mathforum.org/dr.math/ |
