Question 129186

To calculate the {{{surface}}} {{{area}}}({{{SA}}}) of a {{{cube}}}, find the surface area of one side and multiply by {{{6}}}. 

The surface area of {{{any }}}{{{side}}} is the {{{length}}} of a side {{{squared}}}. 



in your example: Surface area {{{SA}}} of a cube with a side of length {{{9m}}} will be: 

{{{SA = 9m^2*6 = 9m*9m*6 = 81m^2*6 = 486m^2}}}
