Answer:
C. $4.38
Step-by-step explanation:
To find out how much paper she covers the box with, you need to find the area of each of the rectangles covered by the box.
First, find the area of the side closest to you.
3 x 8 = 24 in^2
Since the side opposite to it is equivalent, they are both 24 in^2, so multiply 24 by 2:
24 x 2 = 48 in^2
Now, find the sides on the left and right (equal in size).
7 x 3 = 21
21 x 2 = 42 in^2
Finally, find the bottom. There is no top, so there's no need to multiply this one by 2.
8 x 7 = 56 in^2
Add up the sides:
56 + 42 + 48 = 146
Multiply 146 by 0.03:
146 x 0.03 = 4.38
$4.38
Have a nice day!
