Think of a cardboard box. Now imagine unfolding everything and flattening it out as much as possible.

jim_thompson5910 · Answer

it's not to scale (or drawn well), but hopefully you get the idea

anonymous · Answer

oh ok, and what do they mean about a regular polyhedron

jim_thompson5910 · Answer

for part B, it is NOT a regular polyhedron because each face is NOT a regular polygon

a regular polygon is a polygon with all equal/congruent sides
