Anna is wrapping a birthday gift for her brother and has one large piece of wrapping paper left. the size of the paper is 6 feet by 4 feet. will she have enough paper to cover a box that is 12in × 6in × 4in?

Yes, she will have enough paper to cover a box.

Step-by-step explanation:

We are given that Anna is wrapping a birthday gift for her brother .

Size of paper =6 feet by 4 beet

Dimensions of box=

We know that formula

Surface area of cuboid=2(lb+bh+hl)

Therefore, by using this formula

Surface area of box=

Surface  area of box=288 square inches

Surface area of paper==24 square feet

We know that 1 feet =12 inches

Therefore, surface area of paper==3456 square inches.

Surface area of paper is greater than surface area of box.

Hence, she will have enough paper to cover a box .

answer: its because of life

step-by-step explanation: i dont know

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
