If the base of the prism is 3 units long by 2 units wide, then the number of cubes in the base would be 3 x 2 = 6 cubes.

Adding the column of 7 cubes to the base, the total number of cubes needed to fill the rectangular prism would be 6 (base) + 7 (column) = 13 cubes.

Therefore, 13 cubes would be needed to fill this prism.
