I'm assuming the box is a rectangular prism:
They're asking for the surface area so the answer should be 48*2 + 192*2 + 36*2 since it has 6 faces so S.A. = 552 square in.

An airplane is flying from New York city to Los Angeles.The distance it travels in Miles, D, is related to the time in seconds,
deff fn [24]

We have been given an equation d=0.15t that represents the distance an airplane travels in Miles (d) is related to the time in seconds (t).

A. Upon substituting t=1 in our equation we will get,

d=0.15\times 1

d=0.15

We can see that our plane is travelling at rate of 0.15 miles per second.

\text{Speed of plane }=0.15\frac{\text{miles}}{\text{second}}

Therefore, plane is flying at the rate of 0.15 miles per second.

B. To find distance traveled by airplane in 30 seconds we will substitute t=30 in our given equation.

d=0.15\times 30

d=4.5  

Therefore, plane will travel 4.5 miles in 30 seconds.

C. To find time it will take to travel 12.75 miles we will substitute d=12.75 in our given equation.

d=0.15\times t

12.75=0.15\times t

t=\frac{12.75}{0.15}=85

Therefore, plane will take 85 seconds to travel 12.75 miles.
