Step-by-step explanation:
The gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².
<h3>What is the Total Surface Area of a Rectangular Box?</h3>
Total surface area (TSA) = 2(wl+hl+hw), where:
- l = length
- w = width
- h = height of the box.
The amount of gift wrap needed to cover the whole box = total surface area of the rectangular box
l = 20 in.
w = 8 in.
h = 13 in.
Plug in the values into the formula for total surface area of a rectangular box:
TSA = 2(8×20 + 13×20 + 13×8)
TSA = 1,048 in.²
Therefore, the gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

Answer:
234 hours
Step-by-step explanation:
To find the miles per hour, divide 72 by 2 and that equals 36. So 36 miles every hour. So then do 36 × 6 which equals 216. So this is 216 miles in 6 hours, but you still need 0.5 of an hour, so to find how far she travels in 0.5 of an hour, divide the amount she travels in one hour by two. So 36 ÷ 2 which equals 18. So she travels 18 miles every 0.5 of an hour. Then add 18 to the 216 which equals 234.
