A bullet from a gun is fired on a rectangular wooden block with velocity uuu. When bullet travels 24 cm24 \mathrm{~cm}24 cm through the block along its length horizontally, velocity of bullet becomes u3\frac{u}{3}3u​. 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 :
