A rectangular pyramid, with dashed line segments from the top vertex, perpendicular to the center of the rectangle, and from the center of rectangle, to bottom mid-point of right side triangle, and from the top vertex, perpendicular to the bottom edge of the right side triangle. This creates an internal right triangle.Find the volume and surface area of a square-based right pyramid if the base edge has length 6 units and the height of the pyramid is units. Assume the diagram at right is not to scale.  

You will need to find the slant height of the pyramid.
