Leaving Cert DCG Developments and Envelopes: The image shows a cardboard carr

Question

The image shows a cardboard carry-box for a child's novelty toy. A complete surface development of a similar box (without 'gluing tabs') is given in Fig. B-2 below. When the box is assembled, point C coincides with point C1 and point A coincides with point A1. AB is a straight line.

(a) Draw the given development of the surfaces labelled 1, 2, 3, and 5.

Note: Position this view carefully to ensure that the entire answer fits on one drawing sheet.

(b) On a separate diagram draw the orthographic projections, as follows, of those five surfaces, when the box has been assembled:

(i) An elevation in the direction of arrow X.

(ii) A plan projected from the elevation.

(c) Draw surfaces 6, 7, 8 and 9 in your development and also in the elevation, end view and plan.

(d) Draw the remaining vertical 'handle' surfaces (10 and 11) in the elevation, end view and plan and hence complete your surface development.

Note: Both surfaces (10 and 11) meet to form the vertical carry-handle.
