Yolanda makes wooden boxes for a craft fair. She makes 250 boxes as the one shown, and she wants to paint all the outside faces. 6 in.4 in.2 in. Find the surface area of one box. The surface area is square inches.

88 square inches

Step-by-step explanation:

Surface Area =2(lw + lh + hw)

Length, l = 6 in

Width, w = 4 in

Height, h = 2 in

Surface Area = 2(lw + lh + hw)

= 2(6*4 + 6*2 + 2*4)

= 2(24 + 12 + 8)

= 2(44)

= 88 square inches

surface area of one box = 88 square inches

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:
