-platinum has a density of 21.25 g/cc.gold has a desinty of 19.3 g/cc.
\n" ); document.write( "(a)which is larger , a 100 gram cube of platinum or a 100 gram cube of gold?
\n" ); document.write( "Gold is larger, since it's less dense.
\n" ); document.write( "-------------------
\n" ); document.write( "(b)what is the length of each side of a 100 gram cube of platinum?
\n" ); document.write( "Vol = weight/density
\n" ); document.write( "Vol = 100/21.25 =~ 4.70588 cc
\n" ); document.write( "s = cube root of volume =~ 1.676 cm
\n" ); document.write( "
\n" ); document.write( "
