Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Area of a square = $s^{2}$ (s is a side length)

24 = $s^{2}$

$\sqrt{24}$ = $\sqrt{s^{2} }$

$\sqrt{24}$ = s

$\sqrt{(4)(6) }$ = s

What is the surface area of a coke bottle? how do you figure it out?

svetlana [45]

Can or bottle? A can will be the calculation for the surface area of a cylinder which is A= $2 \pi rh+2 \pi r^{2}$ if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that
