The volume of a bus could be 100m^3
I read somewhere that the volume of the mantle was 9.2 x 10^20 m^3
So if the buses held their shape, which of couse they would not, then 9.2×10^18 buses would fit.
Of couse they would compact so this could multiplied by some number greater than one.
Then again the Earths mantle is already pretty crowded so maybe not many buses will fit :)
