If you were to stack all CDs, you would make a tower about 8.0688m tall but would be about 32033576609 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 806.88m long but still be about 333672067 CDs short of circling the Earth... The total mass of all CDs would be about 100.86kg yet you would require a further 459942 CDs to outweigh an average African elephant...
