A box has six sides.
Using the dimensions of the box:
2 sides are 5 x 7
2 sides are 7 x 3
2 sides are 5 x 3
Now calculate the total area:
2 x 5 x 7 = 70
2 x 7 x 3 = 42
2 x 5 x 3 = 30
Total area = 70 + 42 + 30 = 142 square inches.
Answer:
The answer is 142 square inches.
Step-by-step explanation:
Let length be = 5
Let the width be = 7
Let the height be = 3
The gift box is a 3 D box with 6 faces.
So, we get three possible combinations, and each combination is multiplied by 2 for a parallel face.
Hence, we get;
[tex](5)(7)(2)=70[/tex] square inches
[tex](5)(3)(2)=30[/tex] square inches
[tex](7)(3)(2)=42 [tex] square inches
Therefore, the amount of gift wrap needed will be:
[tex]70+30+42=142[/tex] square inches.
