Alright, so this one is a bit tricky. 

You take your bus interior and multiply them all together to find the volume. 
     38 x 8.25 x 7.5 = 2,351.25
Now, you take your 740 BTU and divide by the amount of people (20)
     740/20 = 37
So now you divide your volume by the 37
     2351.25/37 = 63.55

63.55 f^3 is your answer. 

740*20=14800

38*8.25*7.5=2351.25

14800/2351.25=6.294524189

Since the question requires you to round to the nearest hundredth, the answer would become 6.29.
