Brandon has a box 9.5 inches tall, 3.8 inches wide, and 4.2 inches long. How many square inches of wrapping paper does he need t
olya-2409 [2.1K]

Answer:

183.92 inch²

Step-by-step explanation:

To find the total amount of wrapping paper needed, you must find the Surface Area of the box.

Surface area of a rectangular prism is: A = 2(<em>wl</em> + <em>hl</em> + <em>hw</em>)

w = width = 3.8

h = height = 9.5

l = length = 4.2

Plug in the corresponding numbers to the corresponding variables.

A = 2(<em>wl</em> + <em>hl </em>+ <em>hw</em>)

A = 2((3.8 * 4.2) + (9.5 * 4.2) + (9.5 * 3.8))

Simplify.

A = 2((15.96) + (39.9) + (36.1))

A = 2(15.96 + 39.9 + 36.1)

A = 2(91.96)

Multiply.

A = 183.92

183.92 inch² is your answer.
