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!
Answer:
540 in²
Step-by-step explanation:
blue areas = 18 x 4 x 2 = 144 in²
red areas = 9 x 4 x 2 = 72 in²
yellow areas = 18 x 9 x 2 = 324 in²
324 + 144 + 72 = 540 in²
hope this helps ^-^
