Answer:
92 sq. inches
Step-by-step explanation:
Total paper required = total surface area
Surface area of a cuboid = 2[(l×b) + (l×h) + (b×h)],
Where 'l' is the length, 'b' is the breadth and 'h' is the height
For the box, total surface area = 2[(8×3) + (3×2) + (8×2)]
=2[24 + 6 + 16]
=2[46]
= 92 sq. inches
I think you would move the decimal point to the left depending on how many zeros there are.
This is all about proportions. You can make this into fractions:
3/5 = 12/x
A good way to handle this, is to make one of those numbers the same. If you do (3/5) * 4, you would get 12/20 (because 4 * 3 = 12 and 4 * 5 = 20)
So then you have this:
12/20 = 12/x
It's basically a fill in the blank from there. x= 20

Answer:
<em>The app's estimate was 38.4 minutes.</em>
Step-by-step explanation:
Suppose, the app's estimated time was 
minutes.
Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> 
minutes.
It is also given that the error was 20%. So, <u>the amount of error</u> 
minutes.
Thus, the equation will be......
So, the app's estimate was 38.4 minutes.
