The volume of the rectangular prism can be calculated as length x width x height, which is 1 x 1 x 3 = 3 ft^3.
The volume of the cube can be calculated as side length x side length x side length, which is 3 x 3 x 3 = 27 ft^3.
Therefore, the total volume of the composite figure is 3 ft^3 + 27 ft^3 = 30 ft^3.
