Answer:
269.6 square centimeters
Step-by-step explanation:
<u><em>The correct question is</em></u>
The diagram shows the net of a juice box. the box is a rectangular prism. what is the surface area of the juice box? 6.4 cm 4 cm 10.5 cm
we know that
The surface area of a rectangular prism is equal to

where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
we have

<em>Find the area of the base B</em>

substitute the given values

<em>Find the perimeter of the base P</em>

substitute the given values

<em>Find the surface area</em>

substitute

2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
5 24
- -
8 1
Simplify 24 and 8. (8 goes into 24 six times.)
5 6
- -
1 1
or
5 x 6 = 30
You put 4-3 over 7
4-3/7 = 1/7
So the answer would be 1/7
