When 10 cubic feet of water is poured into an empty fish tank (a rectangular prism), the tank becomes ¾ full.
\n" ); document.write( "If the tank is 2 feet 8 inches wide and 40 inches long, how tall is the tank?
\n" ); document.write( ":
\n" ); document.write( "Let's do this inches;
\n" ); document.write( " 2' 8\" = 32 inches
\n" ); document.write( "10 cu ft = 17280 cu inches
\n" ); document.write( ":
\n" ); document.write( "let h = the height of the tank (in inches)
\n" ); document.write( "then
\n" ); document.write( ".75h = height of the water
\n" ); document.write( ":
\n" ); document.write( "Volume of the water
\n" ); document.write( ".75h * 40 * 32 = 17280
\n" ); document.write( "960h = 17280
\n" ); document.write( "h = \"17280%2F960\"
\n" ); document.write( "h = 18 inches is the height of the tank
\n" ); document.write( "that's 1 ft 6 inches
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, find the vol of water using .75(18) = 13.5'
\n" ); document.write( "13.5 * 40 * 32 = 17280 cu inches
