You can put this solution on YOUR website!
well, \"Density=Mass%2FVolume\" ----> \"rho=m%2FV\"
\n" ); document.write( "Since the \"rho\" of wood is given = \"430kg%2Fm%5E3\", also the \"V\" of this wood, we'll use \"Ratio\" & \"Proportion\":
\n" ); document.write( "\"rho=430%28kg%29%2F1%28m%5E3%29=m%2F50%28m%5E3%29\", cross multiply;
\n" ); document.write( "\"430%28kg%29%2A50%28m%5E3%29=m%28m%5E3%29\"
\n" ); document.write( "\"21500%28kg%29cross%28m%5E3%29%2Fcross%28m%5E3%29=%28m%29cross%28m%5E3%29%2Fcross%28m%5E3%29\"
\n" ); document.write( "\"m=21500kg\" ----------------------> mass of \"50m%5E3\" wood
