Calculate the ratio of surface area to volume of an imaginary cubic cell measuring 4mm long on each side?

The answer is 3:2

Explanation:

A cubic cell has 6 sides

= 6 side²

= 6 * 4²

= 6 * 16

= 96 mm²

Volume of a cubic cell

= side³

= 4³

= 64 mm³

The ratio of the surface area to volume of imaginary cubic cell is therefore:

= 96/64

= 3/2

= 3:2
