Surface area is 5454 cm^2cm2, volume is 2727 cm^3cm3

and surface area-to-volume ratio is 22

Explanation:

If ss is the side of a cube, then its surface area is 6s^26s2 and its volume is s^3s3

Hence, if the sides of a cube are 33 inches long

its surface area is 6xx3^2=6xx9=546×32=6×9=54 cm^2cm2,

its volume is 3^3=2733=27 cm^3cm3

and surface area-to-volume ratio is 54/27=25427=2
