prism with edge of base 45 mm and axis 90 mm long has its axis parallel to both
H.P. and V.P. The
lateral surfaces are equally inclined to H.P. It is cut by a vertical section
plane inclined at 60° to the V.P. and passing through the axis at 65 mm from
one end. Draw the projection of the solid. 10 Marks
