Question

What is the surface area to vaule ratio of a cube that is 3cm long ?

Answer 1

Explanation:

Surface area is 54cm²

, volume is 27cm³

and surface area-to-volume ratio is 2

Explanation:

If s is the side of a cube, then its surface area is 6s²

and its volume is s³

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

its surface area is

6×3²

=6×9

=54cm²

,

its volume is 3³=27cm³

and surface area-to-volume ratio is

54/27=2
