1 assuming airy isostatic compensation, the depth to the moho from a point

1 Assuming Airy isostatic compensation, the depth to the Moho from a point located 2 km above the mean sea level is km. (round off to I decimal place). (The depth of compensation T for the crust at mean sea level is 30 km, the density of crust and upper mantle are 2.67 gm/cc and 3.30 gm/cc, respectively).
