If you were to stack all CDs, you would make a tower about 7.914m tall but would be about 32033576738 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 791.4m long but still be about 333672196 CDs short of circling the Earth... The total mass of all CDs would be about 98.925kg yet you would require a further 460071 CDs to outweigh an average African elephant...
