Given the B-Rep (Boundary Representation) model for the pyramid with 4 vertices ([VO] to [v4]) shown below, its base is a square of side length 10 units; the tip of the pyramid is 10 units above the base. (12 marks] a) Draw the diagram in your answer book and label the edges and faces (e.g. with e0, e1, ... and fo, f1, ...). b) Annotate your diagram with the (x,y,z) values of the vertices. c) Produce a table or graph to show the B-Rep of the model. 74 v1 v2 v3 Z vo
