Because of the way traditional maps are drawn you might not have noticed visually, but Africa is huge. How big is it? Well, you could fit the lower-48 United States, China, India, Europe and Japan and they'd all fit.
In fact, the lower 48 United States could comfortably fit inside Africa 3 times. When you look at a map however, it doesn't look as big as we just described. The reason for this is that the traditional maps that we usually see have a skewed perspective due to the fact that the Earth isn't flat like the maps are.
