Africa dwarfs Egypt: about 30,370,000 km² km² against 1,003,707 km² km². At true size Africa is about 30.3× larger — the whole of Egypt fits into Africa roughly 30 times.
The old Mercator map treated both about equally (1× vs 1.3× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Egypt fits 30× into Africa.
