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.
