A water delivery truck with a cylindrical tank measuring 8 ft in diameter and long dispenses water to drought victims in cartons measuring 6 in. × 6 in. × 12 in. How many victims will get a full container of water?

tank volume V = pi (d^2/4) L ft^3
where L is the length in feet which you forgot to type.
volume of carton in ft^3 = v = (1/2)(1/2)(1)
= 1/4 ft^3
so
V/v = pi d^2 L cartons
