part c:

i)faces refer to how many flat faces it has so 6 faces of polygon and 8 faces of triangles so total is 14.
ii)vertice means that for example if there is a triangle then how much point it has so according to this 3 traingles point and 8 triangle so 8 * 3=24

iii)and edges refer to line in a shape e.g triangles havr three line so three edges.
so count how many line are there dont any line again as it third dimensional picture so 24 +12=36.
