Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² = 7² + 4² = 49 + 16 = 65 ( take the square root of both sides )
AB = \sqrt{65} → D
To find how much wrapping paper Taylor needs, we can find the total surface area of the rectangular prism.
= 2(18)(9) + 2(18)(4) + 2(9)(4)
= 2(162) + 2(72) + 2(36)
= 324 + 144 + 72
= 540in.²
So, Taylor will need 540in.² of wrapping paper to wrap the gift.
Best of Luck!
