Lake Texcoco, which became Tenochtitlán is now entirely gone because Mexico City is there. It covered an area of 2.1 x 10^3 square miles. Lake Titicaca in Bolivia, covers an area of 3.232 x 10^4 square miles. About how many times as great is the area covered by Lake Titicaca as opposed to the Lake that the Aztecs built on?
