What will it cost to fill 200 cartons with milk, if milk costs R1200 per kilolitre? Assume that you can buy exactly as much milk as is needed (you don't have to purchase a whole kilolitre if you only need 10 litres, for example).
A dairy truck has a cylindrical tank that is used to transport milk. The tank has a radius of 1,5 m and a length of 3 m.

    Oh, I see, you asked question above assuming I had seen this one.

    volume of tank = pi r^2 L
    = pi (2.25)(3) meters cubed

    1 kiloliter = 1 meter cubed

    However I do NOT know the volume of a carton of milk (perhaps one liter? Perhaps half a liter?)
