You have an order for an 8 gallon aquarium that is 20 inches long and 10.5 inches wide. How deep should the aquarium be? \r
\n" ); document.write( "\n" ); document.write( "this is what I know....\r
\n" ); document.write( "\n" ); document.write( "Common aquarium holds 10 gallons. I know volume of a right rectangular tank is found by multiplying the length of the tank times the width times the height, or V=lwh. I know 231 cubic inches are equal to 1 gallon.
\n" ); document.write( "-----------------
\n" ); document.write( "What's common is not relevant.
\n" ); document.write( "V = lwh & 1 gallon = 231 cu inches is all you need to know.
\n" ); document.write( "----
\n" ); document.write( "V = 20*10.5*h = 8 gal*231 cubic in/gallon
\n" ); document.write( "210h = 1848
\n" ); document.write( "h = 1848/210
\n" ); document.write( "h =~ 8.8 inches\r
\n" ); document.write( "
