Rough estimate: 249k (249 thousand)
The amount of tennis balls is roughly equal to V_bus (volume of the bus) / V_ball (volume of one tennis ball) * packing factor.
Take the following assumptions:
1.) a double-decker bus has a volume of 75 m^3
2.) a tennis ball has a diamater of 6.6 cm (radius = 0.033 m)
3.) the packing factor (which accounts for bus interior ~15% and imperfect packing of balls ~35% lost in "voids between balls" due to spherical shape) is equal to (1-0.15-0.35) = 0.5
Therefore the amount of tennis balls = 75 / (4/3pi0.033^3) * 0.5 = ~249115

Roughly 200000 rounded up if you calculate it regularly I would say 40 could fit in 1 seat and there is probably 70 seats estimated in each row so 40 x 140 is 5600 so do that times 5600 x 20 because it’s half of the tennis balls would be 112000 so we will do 70 of the seats x the 70 other seats would be 4900 x 20 is 98000 and 112000 + 98000 is 210000 so we will add 5600 onto 4900 which is 10500 subtract 10500 from 21000 is is 199950
Guesstimate: 290,000. That's based on a diameter of 6.6 cm. per ball, and dimensions of 2.25m wide, 3.5m high, and 10m long for the bus.

A double decker bus can hold about 80 people, so 100,000 buses could hold 8 million people. The population of London is around 7.5 million so the answer to your question is 'yes'.
In Word: Format > Line Spacing > Double. It could not be simpler!
Right, lets see just how big these buses are to begin with: say 40 people downstairs & another 40 up top =80. So we have 80 x 100 000 = 8 000 000. I don't now just what Londoners are going to say about it, but that is one long convoy ! & I think there are more than 8 million of them.
One ton each. So they weigh the same.
It depends on the copy. A copy coin could have either no gold content or it could be pure gold, it is impossible to say because there is no regulation on copy coins.
