problem: the gasoline tank on a car can be a box with dimensions 1.5 ft x 2.5 ft x 9 inches. How many gallons of gasoline does it hold and what is the weight of the gasoline in a full tank?
\n" ); document.write( ":
\n" ); document.write( "First we find the volume of the tank in cu/ft
\n" ); document.write( "Convert 9 in: 9/12 = .75 ft
\n" ); document.write( "V = 1.5 * 2.5 * .75 = 2.8125 cu/ft
\n" ); document.write( ":
\n" ); document.write( "Convert cu/ft to gallons: (1 cu/ft = 7.481 gals)
\n" ); document.write( "2.8125 * 7.481 = 21.04 gallons
\n" ); document.write( ":
\n" ); document.write( "One gallon of gas weighs about 6.1 lbs (lighter than water which weighs about 8.3 lb per gal)
\n" ); document.write( "21.04 * 6.1 = 128.346 lbs, a full tank of gas. \n" ); document.write( "
\n" );
