Question 678359

if you have a cube and {{{a=5cm}}} is the length of the side of each edge of the cube, than 


{{{Surface_ Area_ of _a_ Cube = 6a^2}}}

{{{Surface_ Area_ of _a_ Cube = 6(5cm)^2}}}

{{{Surface_ Area_ of _a_ Cube = 6*25cm^2}}}

{{{Surface_ Area_ of _a_ Cube = 150cm^2}}}

now I am going to convert {{{a=5cm}}} into {{{mm}}}

{{{a=5*10m}}}

{{{a=50m}}}

then,

{{{Surface_ Area_ of _a_ Cube = 6a^2}}}

{{{Surface_ Area_ of _a_ Cube = 6(50mm)^2}}}

{{{Surface_ Area_ of _a_ Cube = 6*2500mm^2}}}

{{{Surface_ Area_ of _a_ Cube = 15000mm^2}}}
