# Would a lump of gold that big really weigh 70kg?
(I helped save b3ta! Mu Dinofiddler, Sun 13 Jun 2010, 15:30, archived)
# At 17.31 g/cm^3
70kg = 4 litres of gold, not taking into account the malachite layers.

# 4 litres? The world cup isn't that big, is it?

# Give or take a bit, the trophy is
"The trophy stands 36.5 centimetres (14.4 inches) tall and is made of 5 kg (11 lb) of 18 carat (75%) gold with a base (13 centimetres [5.1 inches] in diameter) containing two layers of malachite."

And imagine the amount of Irn Bru in a actual cup that size... admittedly it might corrode through the gold, but still...

# It's not even a real cup :(
Anyway, FIFA say exactly how much of it is gold in that article.

# Imagine if someone dropped it. All that soft gold... it would dent up a bitch.

# hmm
density of gold 19.3 g/cm^3 (grams per cubic centimeter)
world cup is 36.5cm high, and the base has a diameter of 13cm

call it a cylinder so 3.14 x 6.5 x 6.5 x 36.5 (cross sectional areaxlength=volume)
x the density gives 93kg

the given weight of the world cup is 6.175kg

# As the base is the widest point, that's probably about right.
It was just odd thinking that such a small thing could weigh more than a person.

# metal is heavy
especially gold, the density of glass is something like 2.5g/cm^3
