\"h\"= height of the cuboid, in cm.
\n" ); document.write( " The area of the base and the area of the top are each
\n" ); document.write( "\"%285cm%29%2810cm%29=50\"\"cm%5E2\"
\n" ); document.write( "The perimeter of the base is
\n" ); document.write( "\"5cm%2B10cm%2B5cm%2B10cm=30cm\"
\n" ); document.write( "and that times the height \"h\" would be the lateral area
\n" ); document.write( "(the area of the 4 vertical faces), which (in square centimeters) would be
\n" ); document.write( "\"30h\"
\n" ); document.write( "The total surface area of the cuboid (in square centimeters) is
\n" ); document.write( "\"50%2B50%2B30h=280\"
\n" ); document.write( "\"100%2B30h=280\"
\n" ); document.write( "\"30h=280-100\"
\n" ); document.write( "\"30h=180\"
\n" ); document.write( "\"h=180%2F30\"
\n" ); document.write( "\"highlight%28h=6%29\"
\n" ); document.write( "The height of the cuboid is \"highlight%286cm%29\" .
