If you were to stack all CDs, you would make a tower about 8.3808m tall but would be about 32033576349 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 838.08m long but still be about 333671807 CDs short of circling the Earth... The total mass of all CDs would be about 104.76kg yet you would require a further 459682 CDs to outweigh an average African elephant...
