To determine the height of a flagpole standing on a level lawn, a measuring stick 1.80 m long was placed next to it, and the lengths of the shadows of the flagpole and the measuring stick were measured. The length of the measuring stick's shadow was found to be 2.50 m, and the length of the flagpole's shadow was 12.00 m.

Determine the height of the flagpole to an accuracy of 0.01 m.
