Question

What is the surface area, in square inches, of the original box?

What is the total cost, in dollars, of 1 original box?

Answer 1

Surface area of original box:

2((10)(6) + (10)(3) + (6)(3))

= 2(60 + 30 + 18)

= 2(108)

= 216 square inches

Total cost of one original box:

(216 / 144)(22¢ / square foot)

= 1.5 × 22¢ = 33¢
