Part A. Your model is as good as any. It is hard to tell if the label needs to include the descriptor (length = 12 ft, for example). Certainly your model is sufficient for Part B.

Part B. The total area is the sum of the areas of each of the 6 faces of the box. Opposite faces are the same area, so you have
  A = 2(LW +WD +LD) = 2(LW +D(L +W))
Subsituting the given dimensions, you get
  A = 2((12 ft)(6 ft) +(3 ft)(12 ft +6 ft))
  A = 2(72 ft² +(3 ft)(18 ft))
  A = 2(72 ft² +54 ft²) = 252 ft²

The least amount of paper required to cover the box is 252 ft².

Alexus [3.1K]

rewrite -1 1/3 as a decimal: -1.5


-2.1 - x = -1.5

Subtract -2.1 From both sides:

X = -1.5 - -2.1 = -1.5 + 2.1

X = 0.6

I was wondering if you could show How you got the answer. And its not 6 I already tried TvT. Im looking for the surface area of
PIT_PIT [208]

Answer:

22, I think

Step-by-step explanation:

You count all the squares on all of the faces.

So you count the two on the top and double it for the bottom, so four

Then, on the sides you have three so you double that and get six

Next, you double the six squares on the other side and get twelve.

Lastly, you add them up!

4 + 6 + 12

Hope this helps!
