Question

What is the answer A B C or D

Answer 1

We know that the box is a cube, so we know that this box has 6 sides of equal area.

So if one of the sides is 8.5 inches, then since it's a square, we know all of the sides are also 8.5 inches.

So the area of one side of the box is
`8.5in*8.5in=72.25in^(2)`

Then we need to multiply this by 6 to get the total surface area of the box:

`72.25in^(2)*6=433.5in^(2)`

So now we know that the total surface area of the box is C) 433.5 square inches.

Answer 2

To solve this question, use the Cube surface area formula

Area = 6a^2 in which a = edge.

edge = 8.5

Area = 6(8.5)²

Simplify. Follow PEMDAS

Area = 6(72.25)

Area = 433.5

(C) 433.5 in² is your answer
