Nadia plans to paint her jewelry box. the box is shaped like a rectangular prism with the dimensions
shown. which is closest to the total surface area of the jewelry box?

is closest to the total surface area of the box

Step-by-step explanation:

we know that

The surface area of the box is equal to

where

B is the area of the base

P is the perimeter of the base

H is the height of the box

we have

Find the area of the base B

Find the perimeter of the base P

Find the surface area

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

i believe the answer is c.
