Africa dwarfs Bolivia: about 30,370,000 km² km² against 1,090,271 km² km². At true size Africa is about 27.9× larger — the whole of Bolivia fits into Africa roughly 27 times.
The old Mercator map treated both about equally (1× vs 1.1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Bolivia fits 27× into Africa.
