Algebra.Com's Answer #463086 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! While trying to think how to analyze this, no way seems possible without using the density of copper. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Use 8.96 grams/cm^3 for copper.\r \n" ); document.write( "\n" ); document.write( "This density is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That conversion is to let us use units of only kilograms and meters, or cubic meters.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let h = depth of the disc. \n" ); document.write( "Volume of the disc is \n" ); document.write( "This volume, based on the mass and density of the copper must be: \n" ); document.write( "Volume is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Those two volumes must be equal. \n" ); document.write( " \n" ); document.write( "And of course you just solve for h. \n" ); document.write( " |
