Scientists create a futuristic soap bubble in the shape of a box with a square base that contains a fixed volume of air. Specifically, the soap bubble contains 3 cm³ of air. (a) Draw a picture. (b) If the base of the soap bubble box has a side length of 2 cm, what is the surface area of the soap bubble? (c) If the base of the soap bubble box has a side length of x cm, what is the surface area of the soap bubble? (d) Use differentials to approximate the change in surface area if the side length of the base is shrunk from 2 cm to 1.99 cm.

Scientists create a futuristic soap bubble in the shape of a box with a square base that contains
a fixed volume of air. Specifically, the soap bubble contains 3 cm
of air.
(a) Draw a picture.
(b) If the base of the soap bubble box has a side length of 2 cm, what is the surface
area of the soap bubble?
(c) If the base of the soap bubble box has a side length of x cm, what is the surface
area of the soap bubble?
(d) Use differentials to approximate the change in surface area if the side length of the
base is shrunk from 2 cm to 1.99 cm.
