The correct answer is ~8,500 earths made of solid gold.
The following question and solution were offered in a national financial periodical some time ago.
If your distant relative deposited $1.00 in the Bank of Jerusalem when Christ was born, for you to withdraw at the Millenium, and it compounded at 4% annually, what would it be worth in 2000 ?
The answer offered by the periodical: The entire earth, in solid gold. This answer seemed far too incredible to be correct, so I checked it myself.
1.04 exp 2000 = $1.1659 x 10exp 34
Assume $800/ounce for gold
Density of gold is 19.3 g/cc
19.3 g.cc x 1 ounce/28.35 g x (2.54)exp3 cm/cubic inch = 11.1559 ounces/cubic inch
$1.1659 x 10exp 34 / $1,800/ounce = ounces of gold
1.4574 x 10exp 31 ounces/11.1559 ounces/cubic inch = 1.30639 x 10exp 30 cubic inches
1.30639 x 10exp30 cubic inches/1,728 cubic inches/cubic foot = 7.5601 x 10exp 26 cubic feet of gold
Vearth = 4/3 pi x (3,963 x 5,280) exp3 = 3.8376 x 10exp 22 cubic feet.
7.5601 x 1026 / 3.8376 x 1022 = 19,597 earths at $800 per ounce so for $1800 spot price Oct 23, 2021
800/1,800 = .44444 x 19,597 = 8,709 earths
