there are 2 key points in this problem:
\n" ); document.write( "(1)
\n" ); document.write( "The cube is \"submerged\" in the tank. That means the cube is made of
\n" ); document.write( "granite and not styrofoam.
\n" ); document.write( "(2)
\n" ); document.write( "The tank has enough water in it to cover the cube, and therefore
\n" ); document.write( "submerge it. The height of the water must be higher than 10 ft
\n" ); document.write( "when the cube is submerged
\n" ); document.write( "----------------------------
\n" ); document.write( "I can assume the height of the water in the tank is initially \"10\" ft
\n" ); document.write( "Then the volume of water in the tank is 10 x 40 x 50 = \"20000\" ft3
\n" ); document.write( "With the cube in the water, the volume of water + cube in the tank
\n" ); document.write( "is \"20000+%2B+1000+=+21000\" ft3
\n" ); document.write( "The new height of the water in the tank will be
\n" ); document.write( "\"21000%2F%2840%2A50%29+=+10.5\" ft
\n" ); document.write( "The water in the tank rises .5 ft
\n" ); document.write( "(and it does cover the cube, too. If it didn't, the answer would be wrong)
\n" ); document.write( "
\n" );
