document.write( "The volume of the brick is 40 cm x 20 cm x 10 cm or 8000 cubic cm. That volume of water will be added to the tank which has a length of 100 cm and a width of 40 cm. So, the area of the tank's base is 4000 cm. If the water rises 1 cm, it would add a volume of water that was 100 cm x 40 cm x 1 cm or 4000 cubic cm. That isn't enough of a rise in water because we have 8000 cubic cm that the brick displaces. If the water rises 2 cm, it will have risen by a volume of 100 cm x 40 cm x 2 cm or 8000 cu cm and so the answer is 2 cm. </SPAN>\n" );
