An oblique prism with a square base of edge length x units has a volume of 1 half x cubed cubic units. Which expression represents the height of the prism?

The volume of a prism is base area multiplied by its perpendicular height. The square base has area x², so the height is (½x³) ÷ x² = ½x units. Therefore, choice C, ½x units, is correct.
