Hey!
You have to divide the total amount she has by the surface area.
Surface area = 2(wl+hl+hw)
That gives you:
The surface area is 126 ft. Now divide the total amount she has by the surface area.
<em>That means she can cover 9 boxes</em>
I'm pretty sure the answer to your question is -3/5 + 4/5. C.

Part C:
i would graph them in a graphing calculator, and use the functions to see where the 2 lines intersect.
The x value for when they intersect (# of years) is 3.3207883, so approx. 3.3 years for them to be equal
