Well, first of all, the length of the submerged part of the bamboo pole is 1/5 of the total length of the bamboo pole, then the submerged part +0/5 = 1/2+ 1/5 of the total length, then the submerged part is the total length (1-2/5 and then 3/5-

The total length of bamboo pole is 3m, so the mud-soaked part = 3 *1/5 = 3/5m.

Water inlet = 3/5+1/2 =1.1m.
