6 (a) A heaxagonal pyramid, side of the base 30 mm and height 70 mm is resting on its base on HP, having a pair of base sides parallel to VP. A square hole of sides 25 mm is cut through it such that its axis is parallel to HP, perpendicular to VP and intersects the axis of pyramid 22 mm from the base. Faces of the hole are equally inclined to HP. Draw DLS of the pyramid with the hole.
