Question

What is the surface area-to-volume ratio of a cube whose sides are 3 cm long? What is the surface area? What is the volume? What is the surface area-to-volume ratio?

Answer 1

Surface area is `54` `cm^2`, volume is `27` `cm^3`

and surface area-to-volume ratio is `2`

Explanation:

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

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

its surface area is `6xx3^2=6xx9=54` `cm^2`,

its volume is `3^3=27` `cm^3`

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