If you were to stack all CDs, you would make a tower about 7.62m tall but would be about 32033576983 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 762m long but still be about 333672441 CDs short of circling the Earth... The total mass of all CDs would be about 95.25kg yet you would require a further 460316 CDs to outweigh an average African elephant...
