I suppose that it is a kind of heat density but it doesn't seem completely....right.

#### Explanation:

The passengers will produce:

$20 \times 740 = 14 , 800$Btus of heat.

The Volume of the bus (a kind of rectangular box) will be:

$V = 38 \times 8.25 \times 7.5 = 2351.25 {\text{ft}}^{3}$

So we get:

"heat"/"Volume"=(14,800)/(2351.25)=6.3(Btu)/("ft"^3)# in one hour
