You can split a 13-14-15 triangle into a 9-12-15 triangle and a 5-12-13 triangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, the area of the base is (9*12)/2 + (5*12)/2 = 84.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "volume = (base)(height) = (84)(3) = 252
\n" ); document.write( "
\n" );
