A theodolite is set up at station A. The RL of instrument axis is 212.250 m. The angle of elevation to the top of a 4 m long staff, held vertical at station B, is 7^{\circ}. The horizontal distance between station A and B is 400 m. Neglecting the errors due to curvature of earth and refraction, the RL (in m, round off to three decimal places) of station B is __________

A theodolite was set up at a station P. The angle of depression to a vane 2 m above the foot of a staff held at another station Q was 45^{\circ}.
