Where is Zegroes superior intellect when we need it ??
--------------------------------
1.66242 x 108 km2
average depth of 3.940 x 103m which is 3.94 km
$$V=1.66242\times 10^8 \times 3.94 \;\;km^3$$
$${\mathtt{1.662\: \!42}}{\mathtt{\,\times\,}}{\mathtt{3.94}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{8}}} = {\mathtt{654\,993\,480}}$$ km^3
I don't know how many figures are significant :/ I only just saw that bit :(
Maybe Chris can help here ?
