Calculate the surface area to volume ratio of a cube whose sides are 4 centimeters long​

Surface area is   54 c m 2  , volume is  27 c m 3   and surface area-to-volume ratio is  2

Explanation:

If  s   is the side of a cube, then its surface area is   6 s  2  and its volume is  s 3

Hence, if the sides of a cube are   3  inches long

its surface area is   6 ×  3 2 =  6 × 9 = 54 c m 2 ,

its volume is   3  3  =27 c m  3

and surface area-to-volume ratio is  54 =2                                                                    

                                                           27    

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
