\n" ); document.write( "\n" ); document.write( "Surely, you can solve the problem, as @ewattr did it, by computing the starting volume, the ending volume
\n" ); document.write( "and then making subtraction.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "But the meaning of this assignment is to get you an idea, that it is enough to calculate the \"empty\" volume,
\n" ); document.write( "which should be filled.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It can be done in one line and in one arithmetic operation, by multiplying the area by the water rise value.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, this problem teaches you to make your calculations and to organize your solution in a rational form.\r

\n" ); document.write( "\n" ); document.write( "By the way, with such dimensions that are given in the problem, the tank is very instable - it may easily tip over:\r
\n" ); document.write( "\n" ); document.write( "the base area is too small, while the height is too big.\r

\n" ); document.write( "
