If you were to stack all CDs, you would make a tower about 8.058m tall but would be about 32033576618 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 805.8m long but still be about 333672076 CDs short of circling the Earth... The total mass of all CDs would be about 100.725kg yet you would require a further 459951 CDs to outweigh an average African elephant...
