You can put this solution on YOUR website!
Density=mass/volume $\"highlight%28D=m%2FV%29\"$
\n" ); document.write( "The volume of the glass is lenght*width*height
\n" ); document.write( "m=35.303 g
\n" ); document.write( "The thickness of the glass is not in the right units, it needs to be in cm's like the rest of the dimensions before you multiply.
\n" ); document.write( " $\"2.2cross%28mm%29%2A1cm%2Fcross%2810mm%29=.22cm\"$
\n" ); document.write( " $\"V=7.61cm%2A7.68cm%2A.22cm=12.857cm%5E3\"$
\n" ); document.write( " $\"highlight%28D=35.303g%2F12.857cm%5E3=2.7458%28g%2Fcm%5E3%29%29\"$
\n" ); document.write( "Double check this on your calculator, I'm human, not a computer. Math is my thing, and this is a science question. Also some books use kg/m^3 as the prefered unit. Make sure that g/cm^3 is an acceptable unit.
