\n" ); document.write( "how many cubic meters of earth were excavated to make the canal
\n" ); document.write( ":
\n" ); document.write( "Find the area of the trapezoid shape of the canal
\n" ); document.write( "A = \"h%2F2\"(a+b)
\n" ); document.write( "A = \"2%2F2\"(2+4)
\n" ); document.write( "A = 6 sq meters
\n" ); document.write( "1 km = 1000 meters
\n" ); document.write( "6 * 10000 = 60,000 cu meters of earth
\n" ); document.write( "
