A right hexagonal prism has a height of 3 feet and each edge of the hexagonal bases is 6 inches. What is the sum of the areas of the non-hexagonal faces of the prism, in square feet?
There are six "non-hexagonal faces" with a height of three feet and a width of six inches. Six inches is the same as 1/2 feet, and the answer is thus \(6*(3*1/2)=\boxed{9}\) square feet.
