Find the volume of the right rectangular prism packed with cubes. Each cube has an edge length of 1/3 inch. Enter the answer in a fraction and do not reduce. (there are 6 cubes)

The volume of one cube with an edge length of 1/3 inch is (1/3)^3 = 1/27 cubic inches.

Since there are 6 cubes, the total volume is 6 * 1/27 = 6/27 = 2/9 cubic inches.
