When the box is placed on one of its 7 x 12 sides, the water level is 15 cm above the table. If the box is placed on one of its 7 x 18 sides, what will be the water level above the table,in centimeters? \n" ); document.write( "

You can put this solution on YOUR website!
the glass box is 7*12*18 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when placed on 7 * 12 side, volume of the water is 7 * 12 * 15 = 1260 cubic cm.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when placed on 7 * 18 side, the volume of the water is still 1260 cubic cm.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x = the height.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "l * w * h = volume which becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7 * 18 * x = 1260\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get x = 1260/(7*18) = 10 inches high.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's your answer.\r
