James wants to build a ladder to climb a very tall tree.  Each rung of the ladder is 18 inches long and they are 6 inches apart.  If he needs to climb 50 feet how many feet of wood will he need for the rungs? Let's think step by step and output the final answer after "####".

He needs 12/6=<<12/6=2>>2 rungs per foot
So he needs 50*2=<<50*2=100>>100 rungs
Each rung is 18/12=<<18/12=1.5>>1.5 feet
So he needs 1.5*100=<<1.5*100=150>>150 feet
#### 150
