What is the surface-area-to-volume ratio of a cube-shaped cell whose sides are 6 mm long

the answer is in the explanation

Explanation:

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

,

its volume is

3

3

=

27

c

m

3

and surface area-to-volume ratio is

54

27

=

2
