If you were to stack all CDs, you would make a tower about 7.9008m tall but would be about 32033576749 CDs short of touching the moon... If you laid all CDs side by side in one line, you would make a chain about 790.08m long but still be about 333672207 CDs short of circling the Earth... The total mass of all CDs would be about 98.76kg yet you would require a further 460082 CDs to outweigh an average African elephant...
