448 square inches.
The surface area of the box is 448 square inches so that is the least amount of paper needed to cover the box.
Answer:
A) 130
Step-by-step explanation:
(2x + 18) + y = 180 <--- Is True
(4x - 14) + y = 180 <--- Is True
(2x + 18) + y = y + (4x - 14)
(2x + 18) = (4x - 14)
2x + 18 = 4x - 14
-2x + 18 = -14
- 18 - 18
-2x = -32
x = 16
2(16) + 18 = 50
4(16) - 14 = 50
180 - 50 = 130
