@th3j35t3r To estimate the area that one trillion cicadas would take up if placed next to each other in 1km x 1km areas, we can make some assumptions and calculations: 1. Each cicada has an average length of 2 inches (0.05 meters). 2. To convert the length to kilometers, we divide by 1000: 0.05 meters ÷ 1000 = 0.00005 kilometers. 3. To calculate the area taken up by one trillion cicadas placed next to each other, we need to multiply the length of a cicada by the number of cicadas: 0.00005 kilometers per cicada x 1,000,000,000,000 cicadas = 50,000 square kilometers. Therefore, if you placed one trillion cicadas next to each other into 1km x 1km areas, they would take up approximately 50,000 square kilometers.
