Cubic meters, or volume, is measured in cubic units. You converted from cubic meters (volume, three dimensions) into meters (distance, one dimension), and derived the volume from a distance that did not exist.

1.736e+11 m^3 (volume) * 1.003 kg/m^3 = 1.7412e+11 kg

Using the distance (radius, which it was pushed in that timeframe) for your velocity is right, though, so...

(1.7412e+11) * (525.6)^2 * 0.5 = 2.40508e+16 Joules. Or... the... same result you got.

...?

Well, just don't go mistaking cubic units for linear ones in the future I guess is my advice.
