Answer :
Answer:
1) [tex]A_{T}[/tex] = 72 + 24h square inches.
2) [tex]A_{T}[/tex] when h = 10 inches is equal to 312 square inches.
Step-by-step explanation:
You have a gift box with a;
6 inches by 6 inches square base and a height, h.
Finding the total surface area ([tex]A_{T}[/tex]) of the gift box;
[tex]A_{T}[/tex] = 2(6 × 6) + 4(6 × h) = 72 + 24h square inches
[tex]A_{T}[/tex] when h = 10 is;
[tex]A_{T}[/tex] = 72 + 24(10) = 312 square inches
