A bullet from a gun is fired on a rectangular wooden block with velocity $$u$$. When bullet travels $$24 \mathrm{~cm}$$ through the block along its length horizontally, velocity of bullet becomes $$\frac{u}{3}$$. Then it further penetrates into the block in the same direction before coming to rest exactly at the other end of the block. The total length of the block is :

A
$$24 \mathrm{~cm}$$
B
$$28 \mathrm{~cm}$$
C
$$30 \mathrm{~cm}$$
D
$$27 \mathrm{~cm}$$
