If you were to stack all CDs, you would make a tower about 8.2056m tall but would be about 32033576495 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 820.56m long but still be about 333671953 CDs short of circling the Earth... The total mass of all CDs would be about 102.57kg yet you would require a further 459828 CDs to outweigh an average African elephant...
