The Surface area of the cube will be 433.5 square feet. Then the correct option is C.
<h3>What is a surface area of a cube?</h3>
Suppose that: The side length of the considered cube is L units. Then, we get:
Surface area of that cube = 6L² square units.
Bella is wrapping a cube shape box that measures 8.5 inches along each side.
The edge length of the cube is 8.5 meters.
Then the Surface area of the cube will be
Surface area = 6 x 8.5²
Surface area = 6 x 72.25
Surface area = 433.5 square feet
The Surface area of the cube will be 433.5 square feet.
Then the correct option is C.

Hi I just need points if you mark me brain least I will sulfur for you
Answer:
x=4.8
This here you use Pythagorean Theorem.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is c. And the two legs are a and b.
So it'd be 11^2+x^2=12^2
121+x^2=144
Subtract 121 from both sides.
x^2=23
Then take the √ of x^2 and 23
So √x^2=√23
x=4.8
